you could try what works for my ds. He has a bottle when he gets up, then 2.5hours later, some cereal, with water or juice. Then, 2.5hours later, lunch with water or juice. Then, 2.5hours later, a bottle. Then, 2.5hours later dinner with juice. Then a bottle before bed. Phew.
In other words, 3 bottles and 3 lots of solids. Means they dont get as much milk, or as much indigestion as he is eating little and often, rather than many large meals.
