Self sooth this afternoon

Cranky baby this afternoon. Tried waking, tried bouncing, tried stroking, feeding, diper etc. I mean he wasn't even thinking of settling. Finally I threw up my hands, put him in his rocker and said best of luck. After about 15 min, he fell asleep. Perfect. Had a much more successful post - feeding (these have been getting worse since yesterday) & he's out for the count. Not planning on totally going with this method, but it's nice to know it's an option when enough is enough.
