Hi i'm a 2nd time round mum , have a girl who is 12 years old and developt very fast , but my 9 month old son has only started rolling to one side , he cant sit on his own , he wont stand if you try to get him to stand , the health visitor said he is floppy , he wont lift anything , only thing he does do really is eat his hands , he does smile and laugh , but lately he has started wanting to sleep all the time , if u do play with him he gets tired very fast , he goes down to bed between 5-6 pm as i cant keep him awake after then , seems to be going back into a 2 month old sleep pattern, he is worrying me now , anyone had the same problems, please let me know , thanks
