Can anyone recommend

Baby wil be 4 months next week and I won’t to get baby to sleep through night so I can move baby crib into own room. I plan on asking doc what’s the appropriate age to move baby crib to own room and cut out night feeding. Did any of you ladies sleep train and it worked for you? Can you recommend me a method or book.( I don’t really like the cry it out) Baby usually wakes 2-3 times at night for a bottle but just about 2oz and normally during day baby drinks 4-6 oz
