will I have a big baby?

Hannah
So my mother-in-law every time I see her is constantly telling me I'm having a huge baby because my husband was 8.5lbs and had a 11cm head. It's just really irritating me. I was no where near that big. My doctors already told me to it's going to be little considering I'm only 95lbs and 3 mo pregnant. Just wanting some opinions because she's driving me nuts.
