Unless hes sleeping my son doesnt want to lay down on his back anymore. He can now hold his head up with minimal help. He wants to sit up but cant yet. I do tummy time with him. Its a hit or miss on whether or not hes going to enjoy it. I feel like his body is trying to catch up with what his brain wants to do. Is there anything i can do to help him be able to sit up or should I just let nature do its thing? I feel like I shouldnt intervene...I was just wondering if there is any safe way to help him out.
