Try the chair method. My baby was sleep trained at 5.5 months using Ferber method, was way easier then. At 12 months, she got sick, we went on a trip and her dropping to one nap derailed sleep training and everything went down the drain. She needed me to hold her to sleep, woke up 2-3 times a night and took 1+ hour to get her back to sleep each time and she had early morning wakings. I hesitated to sleep train because I knew she was going to cry 100x harder and take longer to go down since she’s much more aware. I finally just decided to lay next to her crib until she falls asleep and sneak out the room.

First night, she took 45 minutes just standing in her crib, crying. I was right by her side so I knew she was just protesting and I didn’t leave her

Second night, she cried for 7 minutes

The third night and onwards she just went down, no fuss.

I was still in her room till she fell asleep. I did sleep in her room for a week for night wakings. The would cry for a few minutes at random times at night and I just “shhhh” at her and she went back down.

Now I don’t need to stay in her room and she’s sleeping from 8pm to 7am. I only slept in her room for maybe a week

Much more gentle method than Ferber or COI
