DD has ADHD (both the hyper and the attention deficit parts!!), and is also very sporty. At age 9, she is doing:
Mon - hockey 1 hr
Tues - football (gaelic) 1hr
Wed - catholic instruction 45 mins
Thurs - guitar 30 mins
Fri - soccer 1 hr, then gaelic football/hurling 1 hr in the evening
Saturday - cub scouts 90mins, sailing club 3 hrs
Sun - Coder DoJo 2hrs, hockey 1 hr
Most of those are actually in school, and Saturday activities are 50 yards apart so we have a picnic lunch together in the break.
She practices instruments (she also has to do tin whistle in school) for 10 mins nightly.
We have done lots of other activities over the years, some in school or afterschool club, others outside in other places. Some of those were other sports while she has also done things like chess club etc in school ECAs.
We think it is a heavy load, but she enjoys them all. We pull back on a couple of things get too hectic, and concentrate on playtime or resting at home. If she didn't have an activity every afternoon after school, she would spend all afternoon in the afterschool club which she finds more boring, and school (well, PTA and the ECA coordinators) are great in having a great range of sporty, academic, and plain fun activities to choose from.
I think we are most likely to drop the local Gaelic club next, as she can't make matches anymore (they changed so clash with sailing - which she adores and will not hear of giving up). And I'd like her to do either book club or lego club in school to replace 1 sport next term. But we manage and it is great that she is so interested in sports and outdoor activities as many of the girls locally really aren't.
