So my S/O and his mom have this crazy idea that the baby is going to be born fitting in size six months and up. My boyfriends mom was telling me how my boyfriend fit in size 12-18 months coming home and in my mind I'm thinking this lady is crazy there is no way he fit into that he weighed about 9 pounds I believe. I weighed 6 pounds as a baby and my son according to the doctors his going to be average (7 pound range). It's so freaking annoying that I get a lesson on what he should wear and what size.
