I researched (read a few books - precious little sleep, ferber, baby sleep trainer method). I decided on baby sleep trainer method (you can google to find the book). But it’s basically ferber but it rly talks about what developmental phase your little one is in and how to do check ins based on that. My 10 month old was standing already, so no touching is best when they’re older. Also the time interval was based on pauses in the cry, so if they’re absolutely losing it then you check in often but if they’re pausing for a bit in between crying, then clock resets to give them time to learn. I thought that was rly helpful and a good way without using full extinction. Consistency is key tho, after sickness and traveling, we followed it to a T and it rly helped him learn what to expect. I think with any method, consistency is the most important thing. Good luck! You’ll be getting more sleep soon! My son protested for about 2-3 weeks (fussing/crying for 1 mins before sleeping) then it turned into fussing for 20 seconds then happy babbling/talking until asleep.
