In my opinion, it seems to help our babies stay alot cooler. Mimi seems to be happier at this point because it is so hot where we live at. She is more use to Downtown Los Angeles where she is use to living by the ocean with my Husband's parents rather than in the valley. I am having to touch up on her just about every two weeks because it seems that her hair grows so fast. I leave her head hair long, but the rest of her I try to keep short for this season.
