What Karmat said: if your camera's cold (we don't know where you are) then give it half an hour to acclimate, or you WILL have condensation issues most likely.
Your camera and two of your lenses seal nicely, however, so you're good to go with either the 24-70 or the 70-200 without a care in the world; decent, fast glass with seals on the mating end, a decent, semi-sealed body. And the 7D runs a nice burst rate. You should have some fun.
Do what you can to shoot from as close to water level as possible for at least some of the pictures. Don't be afraid of a little splash with the L lenses; they can handle it, and so can the body. Have a nice, clean towel with you for mopping up. Low angles work MUCH better than human-eye-level shots, for kids in swimming pools.
I strongly recommend shooting RAW, the lighting may be real quirky and you can sort it out later in the RAW converter. If you're not sure you can cope with RAW, do RAW+JPG (in the menu) and capture both. That way, in the indeterminate future, when you've learned RAW, you can come back to these.
There'll only be one first time, and it is gonna be special. Get those facial expressions!
