Intuitively it seems that you know something doesn't seem right. I question why your Mom accepted and didin't question, that your Dad didn't want to "change your diapers or give you a bath". My ex husband was like that when my daughter's were very young and then I found out. Anyway my intuition told me something wasn't right. I'm not saying this is about your situation , I'm saying trust your self, intuition. It's a natural gut feeling that we all have, don't you think?
