Okay so I'm a first time mom expecting, so I am sorry if this question seems stupid. I just don't know any better... My sister in law has a baby that is 8 months old that I have been watching for her.

All he does is eat and be held. He cries and screams at anything else. He has no interest in tummy time or laying on the floor - even when his mom is here. He is 8 months old - shouldn't he be starting to crawl or at least roll over? Also I wonder Okay, if that was my baby or your baby wouldn't you atleast try to get them on tummy time for a couple mins even if they cry??? My sister in law doesn't do anything that the baby doesn't like... maybe I'm in the wrong? I just want to learn...
