I've always wondered the same thing.
I have 6 babies, and when I do....and that's a really big "when".......I use 1 brush. I've found lately that gauze wrapped around your finger seems to be much easier. I really do try to brush on a regular basis, but, those little monkies can put up such a fight! I consider myself lucky if I get my finger in long enough to get the toothpaste in their mouths.
Little stinker!
