DS just had 12 mth checkup. I like my doctor, but at this appointment, he recommended stopping bottle and nursing saying both are bad for baby's teeth. Instead, I now brush his teeth after nursing, and then lie him down for bed. And we are working to switch from bottle to cup for expressed breast milk and a bit of cows milk he gets. But just now (10:30 pm) DS woke up. I nursed him back to sleep. He was so drowsy (along with me), I skipped the teeth brushing. How diligent do I need to be?
