My son is 3 weeks 1 day and he's very much a momma's boy at this point which is to be expected. He has to be held pretty much all the time and doesn't like to sleep in his newborn sleeper in the pack n play, only in my arms or on my chest. He's even gotten to the point of comfort nursing to sleep. It's been a week or so since I've tried swaddling him, so when he got fussy today instead of nursing him I swaddled him. Instant calm. He was asleep within 2 minutes!! Now to see if he will sleep on his own like this.
