My son is 20 weeks and I'm trying to get him use to sleeping without swaddling. Last night he did great, only fussed two times, fell asleep for about 2 hours, woke up, gave him his paci & knocked out for the rest of the night until 7:30 AM. Tonight he put up a little more of a fight. I'm just going in calming him down with a pat, give him back the paci and walk out. What method are you using if your sleep training?
