My LO drank 400ml a day wen he reached 1 year old . 7oz each feed or equivalent to 7 scoops of milk and 200-210ml of water . He drinks water throughout the rest of the day
just follow as suggestion on the milk tin. nutrition should be come from real food more than milk.
At 15 months, LO Shd be able to eat solids and milk is to supplement only
