Yeah!!!! I am so happy you found us too.. Gotta another product suggestion for your duaghter..
I do have a few suggestions for sleeping caps that do not slip off at night..
I like bonnets for curly hair moreso than scarves.. The bonnets protect the curls so they don't look smushed in the morning..
One product I have used is a sleep cap product called Silky The Cap. Great product, but unfortunately (for a variety of reasons), this company doesn't have a steady distribution deal with the few vendors I know of that sell this product. So it can be hard to find them in stock (They do not have a website either to sell the product..) That said I do know that Extensions Plus (
http://extensions-plus.com) sells these caps on occasion, so give them a call. (I saw the caps at Extensions Plus as recently as last week)
A very similar product is available from this company:
http://www.prettyanntoinets.com/. She sells a VERY comprable product, and she also carries some other sleep caps/wraps. The Tubies in particular are a GREAT product. It states that they are for braids and locs, but it can also be used as a great sleep cap for longer hair styles.
