Newborn Sleep Starter Bundle - Mermaids: Parent Questions Answered

What you get and how the pieces work together

What exactly is in the Newborn Sleep Starter Bundle - Mermaids?

Two matched pieces: a TENCEL Lyocell sleeper as the under-layer and a 1.0 TOG muslin sleep bag over it, both in the watercolor mermaids print. The bundle is priced below buying the two separately.

Why bundle instead of buying a sleeper and sleep bag separately?

The pieces are designed as a set: the sleeper handles the under-layer warmth at 69–73°F nursery overnight, and the 1.0 TOG bag provides the outer layer for everyday nights. Buying them together means one print and matched weights for the same room temperature, so you're not piecing together mismatched layers at 2 a.m.

What is the 1.0 TOG rating for?

1.0 TOG is the everyday weight for the most common US nursery temperature overnight. The bundle is built around that middle range; for warmer rooms above 75°F, add the 0.5 TOG Muslin Sleep Bag in Mermaids, and for colder rooms below 68°F, add the 2.5 TOG TENCEL Sleep Bag.

What's the difference between the starter bundle and the gift bundle?

The starter bundle is for the household using the pieces right away: sleeper plus 1.0 TOG bag. The gift bundle adds a swaddle and a 0.5 TOG bag, packaged for a registry. Both include the same materials and certifications.

Sizing, fit, and care questions

Which sleeper size should I choose?

The sleeper comes in 0–3M, 3–6M, and 6–9M. Size to your baby's current weight rather than stocking ahead; the sleep bag is sized separately at 0–6M (8–18 lb) and 6–18M (18–28 lb).

How do I wash the sleeper and sleep bag?

Machine wash cold and tumble dry low. Do not bleach. Do not iron the printed panels.

Will the print and fabric hold up over months of washing?

Both fibers are described as holding their hand through multiple washes, which is why the bundle is intended to stay in rotation at 18 months rather than being retired early.

Can I return the bundle if the mermaid print doesn't match the nursery?

Yes — unworn, unwashed, in original packaging, within 30 days. The bundle is treated as one item for returns, and free returns apply on US orders.
