So sorry Katherine I can only tell you from experience that it will get better. Once i held ds 3 in my arms it was an instant bond between us and loved him soo much I didn't even care he wasn't a girl, because he was my perfect little boy. My sons loved him soo much and are his best friends. Just watching ds2 be so protective and loving to him melts my heart. I have a feeling this baby is a boy also and I know that all three boys will love him so much that again it won't matter. I hope thats the way it happens for you and are just soo in love with how much your boys love each other it doesn't matter he wasn't your little girl.
