I come from a family of 4 girls, and we got a lot of comments growing up like "wow, your dad is really outnumbered" and such. and I remember hearing someone telling my dad once (when my youngest sister was a baby) that they should try for one more because "the 5th was sure to be a boy". my parents planned 4 children and wanted all girls. and it never seemed like 4 was a big family to us. we knew lots of families with 4+ kids and my dad was one of 10 kids.
recently my pet-peeve has been people being so excited that we're about to have "one of each". DF wanted to have one of each, but I was really wanting two girls. it was frustrating to be upset and scared about having a boy and have people telling me that I should be over the moon because I was having the perfect family. no matter what, people just can't seem to mind their own business about family size and composition.
