So I was soooo confident that I was having a girl! I wanted a boy but I secretly thought baby k would be a girl. I'm so familiar with little girls, I know how to raise them. I've been a nanny for seven years and have worked with (surprisingly) all newborn girls. If I did work with a boy he was a toddler. I'm happy but now kinda nervous! I don't know the first things about what boys like or how to connect with them. Playing with boys has always bored me.. I mean, trains and cars.. Whoop:/. Anyone has a little boy and can give advice on the difference (if any)?
