I remember feeling that way. My daughter wanted NOTHING to do with girly things... even as a toddler. Trucks, cars, motorcycles, etc.... that’s what she wanted.  A doll? No way!!! My husband and my in-laws would sometimes try to push the "girl" things on her, but I always let her play with what made her happy. When she got old enough to pick out what clothes she liked, I allowed her to wear boys clothes because that’s what she was comfortable with. As long as she was dressed decent in nice clothes I didn’t let it become a problem that we were shopping in the boys department. At school she always had a lot of friends, but primarily hung out with the boys because they liked doing the same kinds of things she did. She went to one or two girl sleepovers, but the giggly silly girl stuff was a little more than she could handle! When she was in 7th grade she finally decided she wanted to try wearing a pair of "girls" jeans. That expanded into a few more pairs. And girls shirts. Before long it was no more loose fitting t-shirts with sports logos on them. She’s in 10th grade now and the boy clothes are long gone. She goes to the girls sleep-overs now too and doesn’t hate it like she used to. She still hangs out with the guys a lot. She rides a dirtbike (motorcycle) and she and her friends (boys) like to go riding. But she is an extremely popular and very well adjusted happy young lady. I don’t feel that she changed her ways just because she wanted to fit in. For starters, she’s never been concerned about what people think. She is who she is - take it or leave it. Also, she has a very large group of friends and they’ve all grown up their whole lives together. They would accept her for who she is no matter what.

I would encourage you to let your daughter be who she wants to be. Worry less, and enjoy her more. Everything will work out okay.
