WILL MY BABY BE THE SAME SIZE I WAS AT BIRTH?

Okay I’m a little bit afraid here...let me explain. My dad is the biggest (tall and not fat just big) of all his siblings. My moms side isn’t as tall but not short.

My brother was 9.2 pounds at birth (1st born) my sister was 11 pounds (2nd born) and I was 10.5 (3rd born) we were all long too.

My DH was 8 pounds at birth. His brother was 8.5.

Neither of my siblings have kids yet to compare.

Question is:

Will our baby be huge? LOL What are the chances of me just having a normal sized baby?

I really want to deliver vaginally but if it’s not safe I will have to do a CC.
