Will my baby always have an outy belly button?

No: There's a ligament from the back of the belly button to deep inside the body-- as people grow, the belly button will always pull backwards and become an "innie", unless there is a hernia or something like that. Sometimes belly buttons pop back out in women when that ligament is pushed forward during pregnancy.

No: Most outies turn in by 5 years of age; some stay that way, but this is less likely.
