I don't know why.... but I have this fear of letting my husband watch our son by himself (when he's born).. his dad was abusive, my husband said he will never do that, but a part of me is scared he's going to shake my baby or won't give my baby the attention he needs or feed him.... his brother had told him that he acts like his dad. if he can't stand me crying at night I don't know what he will do to my baby.... he even said that the baby will need to learn not to cry at nothing at a young age but didn't say how young... I don't know why just scared something might happen....
