DS is 13 months and until recently we've never had to sleep train. Two weeks ago (new milestones and teething) he started arching his back and screaming when being put down so we've been holding him to sleep. I'm afraid we've now introduced a crutch so the last couple of days we've tried sleep training, but for today's morning nap the jerks in the condo next door banged the walls so loud the baby's room shook. We ended up giving up and skipping his nap.

I understand they don't want to hear the crying but I don't know what to do! Please tell me about gentle sleep training methods you've tried on your older baby or toddler.
