Should You Swaddle Your Baby for Naps?
Yes. Naps as well as nights.
The startle reflex doesn't keep office hours, and it'll wreck a forty-minute afternoon nap every bit as efficiently as it wrecks a two-hour stretch at midnight, and a baby wrapped for one sleep and not the other has to learn two settling routines where one would do, which is twice the work for everybody and confusing for her. Or so I think. I've known babies who didn't seem to mind.
Every single sleep?
For a newborn who isn't yet rolling, yes.
Consistency is a large part of why any of this works at all. The wrap stops being a restraint and becomes a signal, and a signal only means something if it's reliable, so wrap at bedtime and skip the afternoon and you've turned a cue into noise, and she'll treat it as noise.
The safety rules don't soften for daytime either. On her back, snug at the chest, loose at the hips, face clear, nothing else in the cot, and a nap isn't a lower-stakes sleep however brief it is and however close by you are, and I've seen a great many people assume it is because the sun was up.
The rules in full
The exception nobody mentions
This is the part that gets left out of most advice, and it's the part that counts most.
Don't swaddle a baby sleeping in a car seat, a pram, a bouncer or a carrier.
In a car seat the harness has to sit flat against her body, and a wrap between the baby and the straps changes how the harness holds her in a collision, and loose fabric can work its way up towards her face, and neither of those is a risk you'd take knowingly.
In a carrier her legs need to be in the spread-squat position and her airway needs an open chin-to-chest gap, and a swaddle interferes with both at once, and in a pram or a bouncer she's already semi-reclined and not flat, so the wrap removes her ability to shift if her chin drops, which is the one thing you'd want her to be able to do.
Swaddling belongs to flat, firm, on-the-back sleep. Anywhere else, a muslin goes over the pram hood and never around the baby.
Do afternoons need less?
Often yes, and this is the version of the question that only really comes up in our part of the world, where the afternoon is a different climate from the night. A bedroom sitting at a comfortable 26 degrees under air-con at night can be at 30 by two in the afternoon with the compressor off and the sun full on that side of the block. Same baby, same swaddle, entirely different conditions, and she can't tell you. Adjust the layer underneath and never the wrap. A nappy alone for a hot afternoon, and a short-sleeve bodysuit under the same muslin at night with the air-con running, and the muslin itself stays the same, which is the reason for it. And check the back of her neck or her chest. Not her hands, which run cool on every baby alive and have misled every grandmother alive.

Whether the naps swaddle go first
No. When it ends, it ends for everything.
The reason for stopping is rolling, and a baby who can roll can do it at two in the afternoon exactly as easily as at two in the morning, so there's no version of this where the swaddle goes for nights and stays on for naps, however much better the naps were.
Some parents run it the other way round for a few days as a rehearsal, arms free for one daytime nap while you're awake and nearby, before switching everything that same evening, and that's sensible — I've recommended it — and it's a rehearsal lasting days and not an arrangement lasting weeks, which is where it tends to drift.
When it ends
Two or three in rotation is what makes daily use survivable, because in this humidity a muslin worn through a hot afternoon nap wants washing before the evening, and bamboo has the convenient habit of being dry on the rack by morning without a dryer, which is more than I can say for anything else in my house.
What people ask me
Should you swaddle a baby for naps?
Yes. For a newborn who isn't yet rolling, swaddle for naps and night sleep alike, the startle reflex disrupts short sleeps just as much as long ones.
Should I swaddle my baby for every sleep?
Yes, until rolling starts. Consistency is part of why swaddling works: the wrap becomes a reliable cue and never an occasional one.
Can you swaddle a baby in a car seat or pram?
No. A swaddle interferes with how a harness holds a baby and with her ability to reposition in a semi-reclined seat. Swaddling belongs to flat cot sleep only.
Should daytime naps use a lighter swaddle?
Use the same swaddle and change what's underneath. A nappy alone for a hot afternoon; a light bodysuit under the same muslin at night with air-con running.
Do you stop swaddling for naps before nights?
No. Swaddling ends for all sleeps at once, because rolling can happen at any hour. A few days of arms-free daytime naps as a rehearsal is fine.
