Had a playdate with some daughters and mums from my DD's montessori last week. The DDs are all aged about 4.5 and due to start school in Sept.
I collected my DD after montessori before the play date meeting at the playground, to give her a snack/lunch before we went out. My DD changed into her 'Real madrid' top and shorts - basically her granddad is a Real fan and got it for her when she was about 2. It still fits her as DD is on the petite side. She said she wanted to dress for 'the climbing frame' and also wanted to show off her football top to the other girls (bless!). She's very active/quite sporty and got top of her class in gymnastics so loves climbing, etc.
Usually we have a row about what clothes she wears as she often likes to dress in tracksuit bottoms/t-shirts, etc. Not that I want her to wear dresses, but from a practical point of view, I want her to wear the skirts/dresses she has before she grows out of them! But that particular day, I was tired from work/minding my DSs (2 year old twins) and thought 'what the hell'.
When we arrived, one of the other mother's commented on the way she was dressed - asking 'is she a real tomboy' and when DD climbed way ahead to the top of the climbing frame she said 'oh look at her the mad thing! She means all business the way she's dressed'. She again laughed and commented on how active she was and 'crazy' for climbing so high! (note - girls should be teetering at the bottom of the climbing frame and should know their place! 
I know it was only words, but it was the way it was said. One of the other mothers asked me where Emma got her football top, etc.
The other girls are quite 'girlie', wearing lovely dresses. Part of me was defending her saying it was great she's so active, etc. The other half of me is a bit worried that she won't fit in, esp in school, as may not play well with the girls.
Currently in her montessori, she DOES play with the girls but prefers hanging out with the boys, according to her montessori teacher.
At home, she likes to dress up in the twins boys clothes. She does play with dolls, tea party but much prefers climbing/being outside/active games.
Was chatting to a work colleague about it and she thinks the worst thing I could do it make her 'wear pink' to fit in. I know I can't anyway but I think she's a wonderful little girl, her own person, really active and bright.
But I just felt the other mother's at the playgroup had raised eyebrows.....Should I force her to be more 'girlie'?
