DD had always been a good napper, reliably napping for 1.5-2 hours morning and afternoon, with a 20-30 minute catnap late in the afternoon as well. I used to be able to put her down drowsy but awake and she'd put herself to sleep (she still does this at night with virtually no problems). For the last couple weeks though it has been incredibly hit or miss and I feel like it's dragging me to the brink of insanity.

Shes 5 months old and she's teething...but no sign of the tooth actually cutting through anytime soon She has no issues going down at night though, only for naps.

We have a pretty solid routine: diaper change, walk around for a couple minutes while I rub her back, then go into the nursery, white noise, swaddle and nurse while rocking. I almost never have any issue getting her to sleep, it's getting her off the boob/putting her down that's the issue. She wakes up and starts crying. Today, for pretty much the first time ever, I left her to CIO. It took just over 30 minutes for her to fall asleep. I did full extinction because experience tells me that if I go back in the room we're done for.

We've never sleep trained before because we haven't needed to, so I don't know if I'm doing this properly.

Did you nap train? At what age? How? Did it work?

Please no judgment.
