I have a 12 week old baby. From about 4 weeks old ive been trying to make sure he goes on his tummy for a few minutes per day as I read that they need this to develop the muscles they need to roll over and crawl etc.
My question is, is this enough? And how should he be getting on by now? He doesn't really push up on his arms yet, just arches his back and can turn his head side to side.
