4-1/2 month-old DS has his first two teeth and is exclusively breastfed. Pediatrician says to give him water before bed to rinse out his mouth. I'm not so keen on giving water. I am brushing his teeth at night, but he does often nurse shortly thereafter and most definitely still through the night. I've read/heard different things about tooth decay in breastfed babies. Some say it won't pool, but sometimes milk dribbles out when he falls asleep, so I'm sure there is pooling sometimes. Do you gals do anything special (wipe down teeth with washcloth after each feeding or anything?) to protect against tooth decay or is it something I just shouldn't worry about? TIA!
