This undated photo obtained from a facebook page shows missing toddler Alya Reynolds. Police in Maine are appealing to the public for help in locating the 20-month-old girl who was last seen Friday night. Waterville Police Chief Joseph Massey held a news conference this afternoon to ask anyone with information about Ayla Reynolds to call police. Ayla's father called police yesterday morning to report that his daughter was not in her bed and couldn't be found. She was last seen sleeping at about 10 p.m. Friday by a family member.

WATERVILLE, Maine — Relatives of a Maine woman whose toddler daughter is missing say they were concerned about the girl's safety while she was staying with her father.

Dad Justin DiPietro called police Saturday to report 20-month-old Ayla Reynolds wasn't in her bed at his home in Waterville.

The toddler has a broken arm in a cast.

Her mother's stepsister Whitney Raynor said Monday child welfare agents placed Ayla with her father weeks ago while her mother was in rehab for substance abuse. The toddler's grandmother Becka Hanson tells the Morning Sentinel newspaper the same story.

Mother Trista Reynolds told ABC on Monday she has been seeking sole custody.

A phone number for the father can't be located. Police outside his house Monday said he wasn't there. The Associated Press has been unable to reach his immediate family by phone.

Police say the girl's disappearance is classified as a missing-person case.
