We'll be going to the pool this summer quite a bit. DS is only a month old, so I don't plan on putting him in the water for awhile (when is a good time for an infant to start going in the pool?). DS1 will be in the kids pool so I'll just be sittingon the edge watching him. Is there something I can get to put DS2 in so I don't have to hold him the whole time or keep him in his car seat?
