Ok ladies. I need some advice badly😕

So I have a 6 month old baby and I love him to pieces. I just found out I am pregnant. My plan is to keep the baby but idk how to tell my dad. When I told him I was pregnant with my son he flipped out and it was all bad until he accepted it. I don't want the same thing to happen with this baby. I know he will be mad and so will the rest of my family but no baby is a mistake. (Not meaning I was trying to get pregnant) I wanted to wait 2 years to have a baby.
