Really need help with CIO - if you don’t believe in it please keep scrolling

Hi! I got the go ahead from my pediatrician to start sleep training. I wasn’t sure if I wanted to but my baby is really fighting going to sleep and I just can’t take it anymore. She’s 6 months old.

She’s been crawling since 4 months and overall a very very busy little girl! She never wants to stop playing. I do a relaxing bedtime routine every night and it doesn’t help. We still do it though. She doesn’t want to be rocked or cuddled. Just wants to play play play no matter how tired she is.

So the last two nights I’ve been doing the Ferber method but maxing out at 10 minutes. I’ll go in and pat her back or give her a pacifier but I won’t pick her up. It’s been an hour and a half to two hours of this until she will fall asleep.

I’m having some mom guilt over it but tonight I just could not take it anymore. I’m doing this alone and felt like I was going to have a meltdown over the crying and her fighting sleeping. It seemed like every time I went in it made it worse because she saw me and wanted me to take her out of the crib. When I would do this before sleep training she wouldn’t even let me rock her - just wanted to get down and play. So I decided to just take a shower and let her cry because I really needed the mental break and I knew she was in a safe place and I could see her with the monitor. She fell asleep after 15 minutes of crying.

So now moving forward.. should I just jump ahead to 15 minute intervals? Extinction? I feel so lost on how to move forward with sleep training.
