trying to sit

ok. ken already can sit....on our laps, and also supported. but he is now trying to sit unsupported!!!:) he can last only 10 seconds b4 he topples down. but he is so happy when sitting up on his own! we were toying on the idea of a bumbo....but then, look at this substitute!!!!



of course i was concerned about him being able to cope propped up like that. but according to my parenting bible, What To Expect - The First Year, he MAY learn how to sit unsupported at the end of the 4th month, and also, he will protest and tumble down on his own, if he is tired or if he does not want to do it....soooooo.....
