Don't forget that finding out the gender of your baby is not always 100% accurate. You might think your having a boy just to find out its a girl. I'm sure you would get over the initial shock and love your bub just the same. But you might have feeling of dissapointment if you have just spent all you money on boy stuff.
DH and I both want to find out, if bub wants us to know on the day. But I still plan to stay with fairly neutral stuff, with just a couple of gender specific items untill bub is in my arms.
