Basically wot it says above 
DS is 9.5 months and doing well with a sippy cup for water at meal times and happily feeds himself (and of course turns it upside down, throws it around and generally waters the kitchen!). This is a basic Boots 4+ month free flow one.
He was EBF until 7 months and then combined fed until he was on 3 milk feeds a day. More than happy with a bottle, but now he has 6 teeth and want to get him off this.
The Boots cup he has water from is quite small so was looking for one suitable to give him 200mls of milk from.
Was planning on starting with his afternoon milk this way. Then morning and afternoon before all three (or just two, dropping the arvo feed) by the time he is 1.
Does this sound sensible? Thanks for the advice!
