Capezio Ultra-Soft Tights
If your child finds tights to be uncomfortable, try Miss Christine’s favorite tights, Capezio’s Ultra-Soft. You can get them footless (shown here) or footed.  They sure are soft and comfortable.

You can find them at http://www.curtaincallforclass.com, login: downtown dance lewisburg pa, password: dance2013. Otherwise, most dance retailers should carry them.
