Im sorry you didnt hear boy, I have 2 boys and most likely a 3rd on the way so know how it feels.
Your girls may want to watch sports with you too, and they can still climb tree's and go on adventures, play with lego etc. so try to think of those things to do with your daughters.
My DS says no to me dressing him up in cinderella dresses the spoil sport lol. At least with girls you can do 'boy' things where as with boys you cant really get away with doing girly things together.
Im sure once she is here you will fall in love, I know right now it isnt easy though xx
