My husband feels like I talk to my family too much and we have been having more arguements now that we hav a baby

My husband feels like talking to my family each day is too much. I am Spanish and Italian I told him it’s a cultural thing… he is a white boy… he said it makes him feel like he is married to my family too and not just him and I. I have stopped answering phone later at night because she wants just us time with baby and him. It’s been more arguing since our baby has been born and will be 5 months in a few days. Idk what else to do to make him feel like it’s just us. I feel like I prioritize him and of course baby but my family is excited it’s my parents first grandbaby etc. I also think he is just upset because his family isn’t acting as excited and not reaching out often. His twin brother has three boys and this is my husband first baby. His mom blatantly shows that her other son and his kids are her favorite. Maybe this is why he is also upset? Anyone else of cultural backgrounds understand where I’m coming from that family calls to check each day? Some days a few times… I have told him after he gets out of work we won’t do much calls FaceTimes etc.
