Seriously, my sons sleep wearing very little. They chose it - the oldest one did it first, then the youngest decided that he wanted to be like his big brother. So one sleeps in a pullup, the other in underwear.
But here's how it saves money and the earth:
- Fewer pajamas to buy as they grow
- Fewer clothes to wash and dry (ahh, who doesn't like less laundry?)
- Higher temperature upstairs while the sleep (in the summer, that's a very good thing in Texas!)
So there it is. Sleep naked and save the earth. Tell your friends!
