DD is in year 2 and has only 2 other girls in her year (2 have come and gone along the way). It's mixed classes as only 15 per year, so she's always with either the girls in year above or year below aswell, both of which have 8 girls in.
Being completely honest, I wouldn't choose to have such a small core of girls - sometimes they fall out but have so few of them they can't afford to ignore eachother, and they all seem to prefer bickering to playing with boys!!! Also, cos of the mixed classes, at the start of each year she's adjusting to differenct girls suddenly being in or out of the class.
I don't like it. My girl is very much a girl's girl and she hasn't broadened her horizons to play with boys. It does cause problems. Also, the other 2 girls never have birthday parties and their mums never invite my DD round so she has very little contact with friends outside school.
Academically it hasn't affected her in the slightest, and I agree there is a benefit from performing well next to boys at this age in terms of confidence.
All I'm saying is it is a downside for us of her being in such a lovely, small village school. She still loves school, but would just love there to be more girls!
