My DS is 20 months, and he still drinks milk 3 times a day. He has a sippy cup of milk with breakfast, lunch and dinner. He drinks approximately 16-18 oz. a day (pediatrician says average is 12-16 oz. for his age). When my son was 12 months, he did still have milk in the morning and before bed (as well as with meals...so 5 times a day). We switched him to a sippy cup for snack only first. Then, we used sippy cup for snack and meals but let him keep his milk in a bottle for morning and before bedtime. Once he was used to the sippy cup, we phased out the morning and before bedtime bottles and used a sippy cup.
