DD is, I think, trying to drop one of the 5 bottles a day she is currently having (she is nearly 7m). Unfortunately, she wants to drop the breakfast one - she has only had 1oz this morning and yesterday. Last night she woke at 1.30am and had a full 8oz. How can I convince her it would be better to have a nice full night's sleep and have a lovely big bottle when she wakes up ?
