hi hun, i spoke to my CHN about this as DD does it too (she is 11 months and still has 4 bottles a day and one overnight) and she said they wake and get a bottle once so they start doing it out of habit not cause theyre actually hungry, so if you mix the milk half strength (eg half formula or cows milk and half water) then each night as she wakes decrease the milk til its just water and by the end of the week she will realise it isnt worth waking up for just water iykwim? HTH
