It seems everywhere I look, everyone has a different age that they sleep trained at.

LO is 3 months and definitely cannot fall asleep on her own. She always needs to be nursed or bounced to sleep. And she cannot be soothed without picking her up - she won't take a paci, and gets more upset if I pat/stroke or talk to her. I'm not sure if she's ready for full on sleep training, but I feel like I need to start teaching her healthier sleep habits.

When did you or will you sleep train your LO?
