DS is now 18 months. From about 6 months we set the night routine - warm bath, teeth brushing, clean pjs, last feed and sleep. At 6 months he was having only breast milk and waking up in the night for a few more feeds. At about 12 months, we introduced cows milk as the last night feed and this keeps him going to the morning.
Are his teeth going to be ruined as we give him milk after brushing his teeth?
