Well, we don't have extra money to do too much right now... but right now they are in Awana, kids choir (both free) basketball/tball/soccer (depending on time of year, 8 weeks or so each) and 4-H (1 dollar every other week)
Once we get our credit cards paid off the three bigger girls will have a choice between some sort of music, dance, or gymnastics class (well, the two biggest will choose, the 3yo will take gymnastics.... and the other two will pick DD1-music and DD2 dance just because that's what they'll pick
)
We've picked what they do now because of the low cost involved
The other stuff later because we feel like we can have each of them in one long term active activity (4-H is long term, but not active) and not have too much on our plates. Quite honestly if DD1 wasnt interested in music that wouldn't be a choice because we feel we can give her that basis right now... and she might surprise us and do something more active.
