Did a lookup for hair brushes and found several kinds. If the little one has thick hair like mine and it sounds like she does, I would suggest a wooden handle half round boar bristle brush. The price varies from around 10 to 25 dollars. They come in the 3 or 3 1/2 inch bristle. The flat or paddle brushes just don't get down far enough in the hair to do a good job. The brush I am suggesting is the kind I used all my life because they were the only ones that worked AND did not break every other day.
Hope this helps.
And to keep this on subject.... I've stopped quilting for a while because I am knitting a pair of scarlet red socks. My first pair of socks were practice. One is white and one is gray, but they fit well and keep my feet warm.
