Just wanted to get opinions! My 7 week baby hates tummy time. She hasn’t started lifting her head or turning around when placed on her tummy. The max we have got is maybe a good minute before she starts screaming. We have tried everything to encourage her…laying with her, rattles, toys. But she refuses to do anything except lay head turned to one side. She does not even try to grab anything. I am worried that she is not going to develop motor skills.
