Has anyone sleep trained their baby? And what method did you use? I believe I used the ferber method for my 8 month old ( I think.. I still don't know what I'm doing, it's only been about 3 weeks lol) and he falls asleep pretty quick at night but will wake up several times a night. I go and nurse him every time which I feel like I probably shouldn't be doing that. He's slept through the night a handful of times so I know he doesn't need to nurse. How long do you let your baby cry til you go in and get them?
