I think one of the best things to do is to let your husband talk to the baby's pediatrician about this matter. One of the best things you can do for your baby is to put them on their tummy(with supervision) and let them explore. My daughter HATED tummy time, but it was important to give them the chance to grow (whether they like it or not!) If they are held all of the time, they will never learn to crawl, walk, turn over, etc. They need some time to work on these skills and although they may cry, it is so good for their development.
If your little one doesn't like tummy time ( as mine didn't), put up a mirror for them to see themselves. Or, just spend a lot of time playing the "rollover" game. At least it makes it fun for them. Good luck. He will be walking around in no time, so enjoy your last couple of months of freedom! My daughter didn't crawl until she was 9 mo's, but walked on her own at 11 mo's. It happens so fast! Let me know if you have any questions. It really is so good for babies to play and explore on their own. What a great way to discover what God intended for them!
