stray kittens

A stray cat in our neighborhood brought her 6 kittens into our garage last Friday after we had left our door up.  We know how owns her, however, figure they have kicked her out because of the kittens.  My question is, she and the kittens have fleas.  I figure they are about 3 weeks old give or take a few days.  I treated the mom with all natural flea medicine on the back of her neck, but don't know what to do with the kittens.  Any information you could provide would be greatly appreciated.  

Thank you

The only way to treat kittens that young is with a bath with baby shampoo to mechanically remove the fleas.  Be very gentle and Please dry the kittens with a hair dryer afterwards.
