Then perhaps to go on record to prove who the father is?
I think it may be some deep needed desire to be a family..hoping the man will come back and claim his child. Which is really sad cuz it usually doesn’t happen and you have two or three kids in one home with different names. If I was single and having a child I would definitely give that child my last name. I’m surprised she didn’t do the same with Danneielynn...it would be another way to connect her to Daniel.
