1. No loose blankets

Keep soft objects and loose bedding out of the crib for a safer sleep space.

2. Dress for the room

Dress baby in no more than one extra layer than an adult would wear in the same room.

3. Wearable warmth

Wearable blankets like sleep sacks can be used when they’re the right size and do not cover the head.

Designed around
Reputable Safe-Sleep Basics

Informed by American Academy of Pediatrics safe-sleep guidance

FAQs

Will this actually help my baby sleep longer?

No sleep sack can promise a specific outcome and we won't pretend otherwise.

What Myra does is remove one of the most common reasons babies sleep gets affected:
being too warm,
too cold,
or uncovered halfway through the night.

When that variable is handled, a lot of parents notice the difference.
Some see it in the first week.
Some take longer.
But it's one less thing working against you.

Is it safe? What about overheating?

Myra is built around the same safe-sleep basics the AAP recommends: wearable warmth instead of loose blankets, nothing covering the head, and TOG-rated fabric so you know exactly how warm baby is.

Overheating is a real concern, which is exactly why matching TOG to room temperature matters.
The guide takes the guessing out of it.

What if my baby doesn't like it at first?

Some babies protest the transition, especially coming out of a swaddle.

Give it 3–5 nights.

The sack shape gives legs room to move, which most babies adjust to quickly.
If it's a sizing issue, try the next size.

We offer free exchanges within 30 days for fit issues.

What if it doesn't work for us?

Not the right size or warmth?

If you're not seeing the changes you're expecting, we'll sort out a return too with a 100% refund, no questions asked.

More settled nights.
A morning that feels
like yours again.

When baby is dressed right for the room, one of the most common sleep disruptors goes away. That’s what Myra is built around.

Fewer middle-of-the-night
wake-ups

Being too warm or too cold is one of the most common reasons babies stir. Match the TOG to your room, and you remove that variable entirely.

Less checking. More
sleeping.

The hand-on-chest loop at midnight. The ‘is she too cold?’ spiral at 2am. When baby is dressed for the room, those checks get quieter — and so does your brain.

Longer stretches. Earlier
mornings.

More consolidated sleep at night means waking up at 6am feeling recovered — not wrecked. Small difference in warmth. Noticeable difference in your day.

A bedtime routine anyone
can run

Simple enough to hand off. When the setup is check the room → pick the TOG → zip in, you stop being the only one who can hold bedtime together.

No more guessing between
too many layers

One TOG for your nursery temperature. No stacking onesies and hoping. No 11pm Google spiral. Just the right warmth, matched to the room.

A morning that feels like
a morning

Not every night will be perfect. But when the broken ones get fewer, breakfast happens. Conversation happens. You start feeling like a person again.
