[Sarah Palin] lets Bristol learn and make mistakes on her own, and it's understood that Bristol will support Tripp financially as much as possible — which means buying her own diapers and formula."There's no mistaking that Tripp is her baby, and she is in charge," Sarah explains. "this whole experience has made her grow up so quickly , but she has taken total responsibility and never gripes about it.""I couldn't ask for a better baby," [Bristol] insists. "But the reality is I'm 19 years old and I have a 1-year-old. I wish I could be in my 20s with a baby and not be in my 20s. Just having him so young — I have to work, and I have to provide for him, because I'm a single mom."[In Touch via Jezebel]Related stories:
