If a child is not in the physical custody of the parent or parents, the court, in determining whether parental rights should be terminated, shall consider, without limitation:
3. The effort the parent or parents have made to adjust their circumstances, conduct or conditions to make it in the child’s best interest to return the child to his or her home after a reasonable length of time, including but not limited to:
4. Whether additional services would be likely to bring about lasting parental adjustment enabling a return of the child to the parent or parents within a predictable period.
For purposes of this section, the court shall disregard incidental conduct, contributions, contacts and communications.
