My dd has one and only popped out after she turned 1. First she had an innie then the belly button looks like an outie. The paed said that its nothing to worry about and by the time she gets to 4 or 5 the torso changes shape and it corrects itself. At the moment the torso is more barrel like and in a few years it get longer. like someone said earlier that the only thing you have to watch out for is if the contents comes out....which is rare. The paed said if it cant be pushed back in or it becomes red and hot then to go to the drs. Hope that helps.
