DD has been quite tired this year, I really notice it the last 2-3 weeks of each term. She really needs the 2 week school holidays!
We didn't start anything new but kept up her swimming one night after school and ballet on a Saturday morning. I think the Saturday morning works quite well as her class isn't until 10.30am so we don't have to get up too early and rush around.

I think enrol her, particularly as you promised her and just see how she goes!!
