Hi there,
My little one is 16 weeks, and there is absolutely no way for me to get her on her tummy. I have tried before feedings, after feedings, after her naps...and everytime get the same thing. She starts to fuss, puts her arms out to the side. Now when she knows I am turning her over, she immediately starts to cry. If I leave her on her tummy, she will end up just spitting up.
If anyone has some other ideas, I would be interested in trying them.
