One thing I like with sleepwear is finding the old fashioned cotton gowns. Both girls like wearing them and they keep very warm at night. There are also footie pajamas and they like to double up wearing these underneath the gowns. That is only for the really cold nights but even in the summer time they have light cotton gowns that they wear all the time. If you can find the silk pajamas, they are excellent for summer or spring. If you are looking for girls sleepwear, check out the site above. Lots of different characters and you can choose from silly to feminine!
I have not purchased from this site. All thoughts are 100% mine.
