J,

I appreciate your worries but I think they aren’t worth your time.  Everyone in some way or another bends to society (to follow up your initial comment).  Kids (boys and girls) bend to do things with their peers.  Your daughter has brothers, of course she is going to want to be like them.  But look to the future and realize that she has the ultimate protectors.  :) 

I was discussing this issue with my husband this morning.  His answer "what difference does it make?".  About all of it.  I’m not trying to be mean but really what difference does it make if she likes boy toys, hates dresses, etc......  Enjoy your baby!  Love her for who she is and don’t project on her your worries.
