I have used the fact that my children went swimming in a pool as a substitute for a bath.
Yes, it's true. Sometimes after dinner when it comes time to kick in to get-ready-for-bed mode, I assess whether or not my children need a good bottom-soaking. And, I feel, that if they spent considerable time in a body of water (i.e pool), we can skip the bath and do something else that's fun. As long as it is not too much sweaty fun, like Wii Dance Party.
How about you?
