*936Following the drowning death of his five-year old son, Jaylen, in the swimming pool owned by respondents Alton and Judith Trimble, appellant Jerry Taylor brought suit against respondents for general negligence and premises liability.
We exercise our discretion to treat the premature appeal as an appeal from the judgment and address the trial court's decision on the merits. With respect to appellant's claim of negligent supervision, we conclude that where, as here, the homeowner, having initially assumed responsibility for supervision of the child, turned over such responsibility to an adult close relative who accepted it and did not thereafter relinquish it, the homeowner owed no duty of care to protect the child. With respect to appellant's claim of premises liability, we conclude he failed to raise a triable issue of fact as to causation. Accordingly, we affirm.
FACTUAL AND PROCEDURAL BACKGROUND
In the cause of action for general negligence, the complaint alleged that respondents "failed to supervise and pay adequate attention" to Jaylen. In the cause of action for premises liability, the complaint alleged that respondents "ignored and/or allowed dangerous conditions in and around the swimming pool...."
Respondents moved for summary judgment. In their statement of undisputed facts (SOF), respondents established that on June 1, 2014, they hosted a *937gathering at their home. Jaylen came with his mother, Tywanna Sanders. Neither knew how to swim. When Sanders first arrived, Trimble watched Jaylen in the "kiddie" or wading area, separated from the main pool by a low rock wall, eight to nine inches above the main pool water level.
In opposition to respondents' motion for summary judgment, appellant presented evidence that respondents had made modifications to the pool in 2013, by changing its surface "from a light to a dark color," and adding a Jacuzzi, a waterfall, and the wading area.
Appellant did not dispute that upon arriving, Green agreed to watch Jaylen.
Appellant also submitted the declaration of expert Brad Avrit, a civil engineer and expert in civil and safety engineering, human factors and risk management. Avrit asserted that the pool was in an unsafe condition because: (1) the surfacing on the bottom was dark, obscuring the bottom of the pool; (2) respondents failed to have handy lifesaving equipment, such as a pole, rope or life ring; and (3) respondents failed to provide flotation devices for the children swimming in the pool.
The court granted the motion for summary judgment. The court found respondents owed no duty of care, because "Green had explicitly undertaken supervision of [Jaylen,] and Sanders was on the premises." The court further found that the Avrit declaration "fail[ed] to create a triable issue of material fact regarding whether the pool constituted a dangerous condition," and that *939neither appellant nor cross-complainant "offered evidence showing that any dangerous condition of the pool caused [Jaylen's] death."
DISCUSSION
A. Timing of Appeal
The order granting summary judgment was filed June 8, 2016. Notice was waived. On August 5, 2016, nearly two months later, appellant filed his notice of appeal. Respondents did not file a proposed judgment until August 24, 2016. The trial court entered the proposed judgment on August 29, 2016.
Appellant contends we should dismiss the appeal because the notice was filed prior to entry of judgment and refers to the June 8 order rather than the August 29 judgment. We have discretion to treat an appeal from an order granting summary judgment as an appeal filed after the entry of judgment and elect to do so here. ( Mukthar v. Latin American Security Service (2006)
B. Standard of Review
A defendant's "motion for summary judgment shall be granted if all the papers submitted show that there is no triable issue as to any material fact and that [the defendant] is entitled to a judgment as a matter of law." ( Code Civ. Proc., § 437c, subd. (c).) When a defendant moves for summary judgment, " 'its declarations and evidence must either establish a complete defense to plaintiff's action or demonstrate the absence of an essential element of plaintiff's case. If plaintiff does not counter with opposing declarations showing there are triable issues of fact with respect to that defense or an essential element of its case, the summary judgment must be granted.' " ( Saldana v. Globe-Weis Systems Co . (1991)
*940" 'On appeal from a summary judgment, an appellate court makes "an independent assessment of the correctness of the trial court's ruling, applying the same legal standard as the trial court in determining whether there are any genuine issues of material fact or whether the moving party is entitled to judgment as a matter of law." ' " ( DuBeck v. California Physicians' Service (2015)
C. Negligent Supervision
A defendant is not, by virtue of his or her status as a homeowner, responsible for supervising children who are invited onto his or her property where the children's parents are present and supervising or expected to be supervising the child. ( Padilla v. Rodas (2008)
We find support for our conclusion in Royal v. Armstrong , supra ,
In an attempt to raise an issue of fact concerning negligent supervision, appellant points to evidence that Trimble advised Green to keep Jaylen in the wading area, evidence that Trimble was "shocked" to see Green inside the house, and evidence that Trimble contemplated sending Jaylen home. The fact that an adult responsible for supervising a child has a different view of how to keep the child safe does not require other adults in the vicinity to step in and take control. Young children, even infants, may safely be taken into adult-sized swimming pools as long as the supervising adult uses due care. Jaylen could have been safe in the main pool area had Green stayed close and kept his eye on him, as he said he would. Moreover, Trimble did question Green's decision to leave Jaylen in the care of a minor and obtained Green's assurance that he would not do so again. There is no evidence that Green left his post near Jaylen after that incident. It was not unreasonable for Trimble to defer to Green once Green agreed to assume supervisory duties, and the fact that Trimble remained concerned and continued to check on Green and Jaylen is not evidence of negligence.
D. Premises Liability
An owner of real property is "not the insurer of [a] visitor's personal safety...." ( Ortega v. Kmart Corp . (2001)
"To establish liability on a negligence theory against an owner for injuries caused by a dangerous condition of the property, a plaintiff must prove duty, breach, causation, and damages." ( Hall v. Rockcliff Realtors (2013)
Appellant bases his claim of premises liability on (1) respondents' resurfacing the pool from "light to dark"; (2) their addition of a Jacuzzi, waterfall and slide; (3) the lack of a floating rope or other device dividing the shallow end of the main pool from the deep end; and (4) the ease of access from the *945wading area into the main pool.
With respect to the Jacuzzi, waterfall and slide, we note that noise and agitated water are normal conditions in and around pool parties, regardless of Jacuzzis, waterfalls or slides. Guests create noise and agitate the water by swimming and getting in and out of the pool, and it is unreasonable to expect the owners of a pool to impose quiet and calm. (Cf. Parsons v. Crown Disposal Co . (1997)
The judgment is affirmed.
We concur:

Notes
Appellant's complaint also named Jaylen's mother Tywanna Sanders as a defendant. Sanders cross-claimed against respondents. Sanders is not a party to this appeal. References to "Trimble" herein are to Alton Trimble.
Sanders did not bring a flotation device for Jaylen and testified she rarely required him to use one. After Trimble agreed to watch Jaylen, Sanders left to go to the store. When she returned, Jaylen was still in the wading area being supervised by Trimble. Sanders spent most of the day inside the Trimbles' house.
Green testified at his deposition that when he arrived at the party, he told Trimble he would watch Jaylen. Trimble had not put Jaylen in the main pool because he was not willing to watch him there. Green said he would "sit there and watch him ... in the shallow end of the main pool." Green also testified that he never turned over his responsibility to watch Jaylen to anyone else.
Sanders testified that she saw Trimble in the house and did not ask him who was watching Jaylen because she assumed another adult or group of adults was doing so. Sanders further testified that Green had supervised Jaylen at other pool parties.
Appellant did not dispute that respondents obtained a county permit when the modifications were made.
Appellant claimed to dispute a number of the facts set forth in respondents' SOF, but instead referenced evidence pertaining to independent facts, which should have been set forth in his counterstatement of facts. Despite this procedural irregularity, we consider all the evidence presented in the opposition.
Avrit claimed that at the time of the incident, respondents' swimming pool was not maintained in accordance with the applicable building codes. However, the only code he referenced stated: "The owner or the owner's designated agent shall be responsible for the maintenance of buildings and structures...." Avrit also claimed that respondents were "in violation of the recommended guidelines and industry standards for swimming pools" by failing to provide arm flotation devices to the children on the day of the incident. However, the only standard he cited was from a booklet entitled "Overall Safe Operation and Maintenance of Your Inground Pool," published by the National Spa & Pool Institute, which stated: "Plan ahead for potential emergency situations by owning and being familiar with basic lifesaving equipment and procedures. Have at poolside a device such as a solid pole, a rope or a life ring, which can provide immediate assistance to a person in trouble. Practice using these devices correctly to be ready in an emergency. Only use these devices for emergencies. Do not allow children to play with lifesaving equipment."
Avrit cited a booklet published by the National Spa & Pool Institute, "The Sensible Way to Enjoy Your Inground Swimming Pool," for the proposition that "For safety's sake, any user of your pool must be able to clearly see the bottom drain or bottom of the pool...." The sentence, quoted only partially in the declaration, concludes, "so as to be able to make intelligent decisions about jumping, sliding or diving."
Respondents raised a number of objections to Avrit's declaration. The trial court did not rule on the objections, but the language quoted above indicates the court considered Avrit's declaration in making its ruling.
Nearly two months passed after the court issued its summary judgment order before appellant noticed the appeal; he could reasonably have been concerned that the judgment or notice of its entry had been lost. Had respondent promptly filed the proposed judgment, any confusion could have been avoided. (See Mukthar, supra, at p. 288,
Englund v. Englund, Moses v. Bridgeman, and Herron v. Hollis all involved parents of drowned children who sued the owner of the property on which the tragedy occurred; all three courts concluded that when a parent was present, it was the parent's responsibility-not the property owner's-to supervise the child. (See, e.g., Englund v. Englund,
Our research has found no California case in which a negligent supervision claim arose in the context of a pool party. But such claims have arisen in other jurisdictions, and courts have expressed no hesitation in concluding that a homeowner who has volunteered to supervise a young swimmer may be liable if he or she does so negligently. (See, e.g., Royal v. Armstrong (2000)
In Englund v. Englund, where the plaintiff similarly contended that summary judgment was improper because "the homeowners admitted their negligence" by telling the plaintiff " '[w]e just got too relaxed,' " the court stated: "We have previously found that the homeowners did not have the primary duty to watch Lauren [the victim] ... [E]ven if the homeowners acknowledged that they were lax in their attention to Lauren, this does not relieve plaintiff of her duty to Lauren and does not render the homeowners liable for Lauren's death." (Englund v. Englund, supra,
Proof that the defendant violated a statute or regulation, including administrative regulations and local building code provisions, may give rise to a presumption of negligence in specified circumstances under the doctrine of negligence per se. (Evid. Code, § 669 ; Elsner v. Uveges (2004)
Avrit also blamed the failure of respondents to make available arm flotation devices or "floaties." Appellant does not mention this in his argument or suggest that it contributed to the "dangerous condition" of the pool. Nor does he contend that a pool owner is obliged to provide flotation devices for every child who uses the pool.
Neither this Court nor the trial court was required to accept Avrit's opinion that the color of the surfacing contributed to the incident. An expert opinion that does not contain "a reasoned explanation illuminating why the facts have convinced the expert" need not be relied on. (Jennings v. Palomar Pomerado Health Systems, Inc. (2003)
We note that a Centers for Disease Control and Prevention advisory attached to Avrit's declaration provided the following advice: "When a young child or inexperienced swimmer is in or around water, always be within arm's length.... Drowning can happen very quickly and quietly."
