Re: 9 month old won't stay on belly?
Why are you wanting him on his belly at this point - he is mobile and doing what he should be and getting the exercise - the tummy time is for the little ones... let him do his thing...he'll be pulling up and cruising before you know it - don't rush it as then life as you know it will be over soon... I would worry more about baby proofing... it went so quick for us.. once my son sat up, nothing stopped him... he took to cruising right away. (yesterday I put him on stairs for the first time and he went right up with no problems at Grandma's house and freaked her out - while I was laughing in delight taking pictures)
Mom to my wonderfully sweet toddler who is the joy of our lives.
