We need to start brushing our son's teeth with a "real" brush (we had a glorified chew toy until now). Does anyone have any recs for a simple, inexpensive toothbrush for a baby (small, soft bristles)? All of the toothbrushes I saw online and at my local drugstore run about $4 a piece because they have some character printed on them or other gimmick. Unfortunately, I think this is one of the few things you can't buy used.
