Last winter, when my kids were in daycare, our peditrician recommended that I strip the kids and give them a bath every day when we got home. He believed that it could drastically cut down on the germs brought into the home. I did just that, not only because of the germs, but the kids played hard at daycare. I also liked doing it when we got home because that would be one less thing we had to worry about before bedtime.
Now that I'm a SAHM for a while, the kids get a bath about twice a week. They just aren't sweating and getting grimey. My son has eczema too and I've heard conflicting opinions where some doctors believe an everyday bath helps to keep the skin moisturized if something is use to lock in the moisture afterwards (like Aquaphor).
I sure don't miss giving them a bath every day. The time it takes to give two little ones a bath plus the laundry it generates with towels and wash cloths is amazing.
But, I'm probably not the best person to be asking about this because I recently got blasted here on the DIS by some folks who thought it was nasty that I let my kids pee more than once in their diapers before changing them. Heehee!
