I wanted to know and was going to know whether Dad2be wanted to or not. When it came to the ultrasound it was a choice of him staying or leaving but he decided he really did want to know. I would have bought blue regardless of gender because I HATE pink but I have been having a lot of stress and panic about bubs and wanted to be able to name him and start talking about him like a real person (because to me he is) so I can connect to him better. If she wants to know and you don't could she find out and keep what she buys at a relatives house or something so it doesnt spoil the suprise? We were going to have everything left at my grandmothers house if Dad2be decided he didn't want to know
