Day 168 of 300 · Week 23
Swaddle off, pacifier loose
Last reviewed · 3 min read · 9 sources · Plain-text version
A baby who tries to roll is a baby who's done with the swaddle, tonight. The pacifier stays, unclipped. Back to start every sleep, in your room, and leave them be once they roll both ways.

If your baby is still swaddled for sleep, today is the day it ends. Not because of a date, but because of what their arms and legs have started doing.
Heart
Stop swaddling once your baby tries to roll, and don't hang a pacifier around their neck or clip it to clothing for sleep (Moon, AAP). The reason is blunt: rolling while swaddled raises the risk of suffocation and SIDS, and swaddling sleep sacks that compress the arms and chest should stop at the same point. A wearable blanket that lets your baby move freely is fine (Moon & Glassy, AAP). In a meta-analysis of four studies, SIDS risk with swaddling was highest when swaddled babies were placed on their stomach or side, and limited evidence suggested it rose with age (Pease et al., 2016). At 24 weeks, with a baby who rocks and twists, the swaddle has run out of road.
Head
The rest of the rules haven't moved. Back to sleep, on a firm, flat surface with only a fitted sheet, in your room but not your bed (Moon, AAP); room-sharing is for at least the first 6 months (Moon, AAP). Always start your baby on their back, but once they roll both ways comfortably, you don't need to flip them back (Moon, AAP). Never use weighted sleep sacks, swaddles, or blankets (Moon, AAP). And one arm out is a comfort step, not a safety step: there's no evidence about SIDS risk with arms in versus out (Moon & Glassy, AAP). If "one arm out" has been your compromise, it's time for both.

Arms free tonight
Time: 5 minutes at bedtime · Safe sleep for a baby who rolls in the guide
If your baby still sleeps swaddled, or in a sack that pins the arms, switch tonight to a sleep sack that leaves both arms free (Moon & Glassy, AAP).
Take off any pacifier clip, cord, or string before sleep (Moon, AAP).
Lay your baby on their back on the fitted sheet, nothing else in the crib, in your room (Moon, AAP).
Keep the bedtime routine exactly as it was; the sack is the only change (AAP).
Make it work:Put the swaddle blanket somewhere you won't reach for it at 3 a.m. The drawer, not the crib rail.

For you

The first night of a new habit is the hardest, for both of you. Expect a worse night than usual and plan for it: nap today if you can, and go to bed right after the last feed (Moon, AAP). The rule that matters most on a rough night is the one about where you feed: skip the couch and armchair, and if you nod off, move your baby to their own sleep space as soon as you wake (Moon, AAP). A bad night in a safe crib is a bad night. That's all it is.
If you're the partner: tonight is yours. Take the wakes, and don't offer the swaddle back as a mercy.
