Wanna some funny metal more-than-a-simple-cover? Do you remember Miley Cyrus' "wrecking ball"? here you are!
It is! That happened to me more than once or twice per child, but as long as they are still that young it doesn't even smell that much. And look, the kid seems to be happy! (Just like mine were. I think babies complaining about full diapers are a myth invented by the diapers industry. I have never met a baby who even cared)
