Breaking the Bottle association

Hello all,

I need some advise on routines and breaking the bottle association for my 14 month old.

He has never been the best sleeper at night, sometimes would sleep through and other times not, but up until he was 1, I just put that down to being young and needing extra feeds at times as he has always been a ravenous baby.

When he was 1, he had 2 nasty bouts of tonsillitis and has not got an association with the bottle, mainly at night. If he wakes he won't go to sleep unless we give him a bottle. It just tends to be once a night, but can be up to 3 or more times if he is sick/teething etc.

I am 16 and half weeks with our third and really need to get onto this as I want to put him in a room with his brother soon and can't do this until I've sorted out his routine/sleep habits.

Is there anything I can read, or anyone who has had the same problem and a good result please let me know.
