I have no idea of the child minding part, but what is your DD like at the pool or with other people. Is there anyone you can go with who also has kids and take turnsminding them? Just an idea as that is what we do here, there's a few of us....one person does say 3 laps whilst we amuse the kids and take it in turns that way. Not sure if it will work for you just an idea, living with husbands who are always away for work we come up with ways to make things work or I myself would never leave the house. I had a friend bring her little boy to Zumba the other night, he loved it!.........our gym doesn't even have child minding
