This has always worried me.
I remember taking my dd to buy a new coat, when she was maybe 6 or 7 (and still liked girls things!). She tried one on and stood in front of the mirror and the female assistant asked what she thought. My dd replied "I look like a princess" and the assistant looked quite surprised. Then she gave a huge smile and agreed that she did look like a princess, but as she was packaging up, and out of dd's earshot, she said "do you know how rare it is for girls to be so positive about themselves like that? I can't tell you how many girls I see, who just get embarrassed, don't like to look at themselves or don't see a princess".
I remember wondering at the time what age that self consciousness and negativity started to set in and was determined to do what I could to strengthen dd's self belief in the hope she could ride the storm.
I genuinely think gymnastics, and maybe sport generally, was the best thing she could have become involved with. She is 100% proud of her body and her muscles and I catch her checking herself out all the time! At sports day she was in a mixed running race and some of the boys were also a year older, but she believed she could win and she ran as if she could (she was a close second to a very sporty boy). Even now there were a couple of girls who set off down the track with barely any effort at all and just looked totally embarrassed by the whole thing. I completely understand not everyone likes sport and sports day is excruciating for kids who don't like sport (although truly I thought that happened later than 9 & 10)- but I just loved the belief my daughter had that she could win if she tried. And afterwards she was so happy "did you see how fast I ran, I felt as though my feet hardly touched the floor". And then she spent some time experimenting to see if it's possible to actually run so fast her feet don't touch the floor
I hope she sticks with the gymnastics long enough to get her through. I hope that if she quits next week she has learned enough about how amazingly strong and capable she is.
But I think there is a whole separate pressure which starts to kick in and which says that competitiveness is to be frowned on. We've discussed before how people don't bat an eyelid when kids practice piano every night and artistic skills are celebrated, but if you have a talented sports child people are much quicker to think it's pushy and/or that sporting achievements are not somehow as important or useful and musical or academic ones. Everyone has to be a winner, when it comes to sport.
It's a bit of a minefield, but I think she'll come out ok!
