Ftm sleep training questions

Hi!

So I'm reading a lot of posts on sleep training and have a few questions.

1. Which method are you using/ is it working?

2. Are you starting sleep training with bedtime first? Nap time first? Or both at the same time?

3. How old is your baby?

4. Where does your baby normally sleep/ are they still taking a bottle during the night?

My baby struggles with self soothing and is also going through the sleep regression. I want to start sleep training soon!
