We were told by a dentist friend that before babies get teeth, you're supposed to wipe their gums with a clean washcloth during bath time. Then, once they actually get a tooth, you're supposed to start brushing it twice per day. He also said that babies should see a dentist when they get their first tooth. Honestly, the seeing the dentist part surprised me. The thought of our busy, busy, busy baby having to sit still and open her mouth for a dentist sounds a bit...impossible!
One of these days I'll get a picture of her sharp (says her her nursing mom) little tooth ;)
