My son is 9 months old. If he is awake, he has been crawling for 3 months by now and he pulls himself up and walks holding onto furniture and stands up on his own also.

What my problem is, he likes to sleep on belly, he rolls onto belly quite soon after he has fallen asleep, but then he crawls in his sleep also. He just crawls until he bumps his head to the bed, sits sits up and starts crying. Or the other option is, that he bumps his head pulls himself up, still eyes closed and starts crying. We do roomshare, he sleeps on his crib in our room. Bumping his head doesn't hurt him, just wakes him enough for him to sit or stand.

What can I do to help him not do that way? Because if he wakes, only way to get him asleep fast is to nurse him. (during daytime he is not fed to sleep, he falls asleep himself). I am exchausted of waking 4-5 times a night because of it.
