My 11 month old is social, babbles, smiley, eats fairly well, sleeps well but physically doesn't really do anything! He can sit up but only if put in that position
He can't sit himself up from lying down, he can't crawl, he can't pull up to standing, he can't stand, cruise, walk. He can roll but doesn't much.
At what point do I raise it? If I stand him up holding on to something he will weight bare for maybe a couple of seconds (but not well) and then his legs go like jelly. Is there potentially something wrong?
