i breast fed sophie before her night sleep up until 18 months, yes it was tough, very tough for the first few night, she cried, needed more cuddles extra, but we introduced sing twinkle twinkle little star as her new bedtime thing and afte a few weeks she got the hang of teh change and now runs to her bed after singing!! id start something now such as reading a book then slowly cut back teh bottle until hopefully you only need to read a book ,and see how that goes
