So I don't know a lot about sleep training/cry-it-out/ferber/extinction/etc. I've heard about it, but I don't really know whats what.

Our pediatrician recommended today at our 4mo appt that we sleep train because LO has been screaming when we try to rock her to sleep and she said it will just be better when she learns to self-soothe. She also said she thinks we could/should swaddle-wean at the same time. Oh also, the screaming is due (I think??) to the 4mo sleep regression.

I'm feeling really torn about doing the sleep training because 4 months seems young to me, and because I feel like the 4 mo regression is hard on HER (not just us)... and swaddle weaning + sleep training while she's going through some hard stuff seems like a lot. But I do see the ped's point about ripping the band-aid off and getting her sleeping swaddle free on her own now while her sleep sucks anyways so when we come out of this we have a great sleeping baby.

So I'm considering it.

Ped said her recommendation is to just sit next to the crib and soothe baby with pats and calming words, but not pick her up. Just let her cry until she falls asleep. Start with naps and then add nights once naps go well. Is that a "method"?

Can anyone explain briefly what other methods there are? (some that may have a bit less crying? if that is even possible?). Sigh. I guess I just need a primer on my options. I tried googling but everyone claims to have the best method and I'm a bit overwhelmed by options and not sure which ones are semi-legit.
