K.F.
I had a foster child with a belly button hernia and his had popped out. The Dr.'s were not going to do surgery unless it was still there after the age of 5. They just told me to keep an eye on it and if there was any change to bring him in. They also said to be careful to not overfeed him. All of that just to let you know that if it is a hernia that you should not freak out. Just take her to the Dr. to make sure that you have covered all of your bases.
