Father in law

My husband and I were ecstatic after we found out we were pregnant. We went to our family members one by one and announced the news and everyone was super excited. Except his dad. Who I have always had a pretty decent bond with over the last four years. We showed him the test that day, and all he did was nod his head, and say "Yup" and went about his business. My husband and I both agreed that we honestly do not care who does or does not support our decision to plan our pregnancy. I was 5 weeks pregnant when we told them. I am now 23 weeks pregnant and his dad has yet to even ask to see an ultrasound or even ask what we are having. He has shown absolutely no interest in our pregnancy which baffles my mind because when his oldest daughter got pregnant with her child after two months of being with her (tool bag) of a boyfriend, he was so excited. My husband and I have been together for four years. Like I said, we do not care if he is happy or not, but am I wrong for not wanting him to be notified when I go into labor? I don't think he's earned the right to be one of the first people into the room after she's born. He hasn't shown any interest or care about her now, so what makes it different when she's here?
