Our son is 18 mo old. He's active, loving and incredibly curious. At night time, however, we battle to get him to go to bed. Bedtime is at 9pm. Normally he will wake up 2-3 times a night. Each time he wakes up we give him a bottle of milk. At our last well baby check up I ask our peditrician for advice. He gave us the info about cavities and the possibility of increased ear infection, but how do we break this bad habbit?
