My husband is a mess!

So my husband just came home and rubbed my belly smiling saying it seems like you get bigger like every 2 days... Yeah baby I know! Lol I'm 17 weeks, were having a boy and I've always had a super flat stomach and big hips. I guess that's why I'm popping out? I'm not sure but I definitely eat too :-) I'm 5'9 large framed woman, my husband is 5'10 large and broad shoulders and on my side all the men in my family are big ol boys so we both feel like we are going to have a big boy. We hope so!
