I'm not going into detail about this, but I know a person that has a child that's a little younger than Ava that's not meeting her milestones. She's not grasping, flipping over, sitting up, her head still wobbles, and she hates (cries hysterically) when she puts her on her tummy; whereas at that age Ava was doing all that and more. She loved being on her belly, she was flipping over from both sides, sitting up, playing with toys, etc. I hate to compare, but Ava's all I have to compare. I'm actually very concerned. I don't know if I should say anything. She's a very close person to me, but can get easily offended. I'm concerned for the child. The child's problem is actually that her parents don't do anything with her. Her mother told me to my face that the only time she puts her down is in her swing or in her bassinet. The father is clueless. He doesn't do anything with her either. I've seen parents that put children in their swings all day b/c of the type of work I do, but I never thought this person would be this type of mother until now. She thinks it's okay. I'm baffled.
