Hi im having the sam problem with my daughter she is 21 months, and wakes up at least twice every night, she to asks for her cup of milk and drinks it all, so im presuming she most be hungry, ive ried giving her more food in the day but it doesnt help ivealso tried giving her supper but she still wakes. when she does have a bottle in the night a lot of the time she brings it back up 10 mins after, so she wakes the next hour asking for another drink. Sorry i cant help but just to let you know your not on your own, if i come up with a solution i'll let you know. keep us posted x Estee x
