content: I liked these the best when my baby was 16 lbs. but now at 20lbs he leaks through every one of them in 2 hours or less. The 4's fit a little too big and I know he's almost ready but these are supposed to be good to 28lbs and they are not. I have almost an entire case of these that I am donating because I don't trust them. Size 3 of Sam's Club brand is working WAY better than these and cost less too.
