Ross just try stop giving them bottle milk in the middle of the night it will be very difficult for the first few nights but once they get used to it they wont be asking anymore. Just make sure they have milk or snacks before bedtime. We stopped giving my wee boys ages 13 months and 27 months milk in the middle of the night when they were 11 months but i make sure after dindin they get fruit snacks and milk before bedtime and that really helps.
