I always wanted a son, though I love my daughter, I still crave for a son. Is this feeling normal to live with or will it affect my relationship with my daughter?

I always wanted a daughter, got one, then wanted another, got one - i was exceptionally blessed. It's alright to wish for a son or daughter, but if you have the other one, it is more important to give your baby ALLLLL your love, care, attention and more than the best :)
