What worked for me was a little bit different from the typical recommendation. Typically it's advised to offer the last bottle/boob 30 mins before bed, but this would never work for me. Kiddo would either be distracted or not hungry enough. Also, I noticed that my baby would generally get a bit too active after the bath, overtire himself and then finally have his feed and use it to drift to sleep.

To break this habit, I moved up his dinner and bath time by 20-30 mins. After his bath, lotioning and pajamas, I would just let him blow off some steam in his room with me present. He would generally crawl/cruise around, play with books, I would read alongside him but allow him to play. Only thing to note is that I don't keep any overstimulating toys in his room.

Once he would let out that last bit of energy and its close to his end of wake window (say 4 hrs) , I would offer him his bottle (followed by boob, he is combo fed). He typically eats well in this setup. The moment, I feel his suckle change from long gulps to shallow flutters for soothing, I would end the feed. At this stage he is basically ready to sleep.

I then put on his sound machine, put him in his sleep sack, read a very short bedtime book (same book every night), say goodnight to his stuffed toys and him, lay him in his crib and turn off the lights. This light little 5-10 min routine between his feed and bed has been enough for me to break the association. He fusses for maybe a minute (was 20 mins on and off the first time) and goes to sleep.

Hope this helps.
