The curation

Why these two pieces.

The First Nights Kit is the smallest layering system that covers the first three months at home — a bodysuit against the skin and a swaddle on top. Sized, weighted, and toned to wear together.

  1. i.

    A bodysuit against the skin.

    GOTS-certified organic cotton, sized 0–3M to fit the average newborn through their first growth spurt. Snap closure for the changes you do not see coming, gusset opening for the ones you do.

  2. ii.

    The Swaddle UP for arms-up sleep.

    The moro reflex peaks between weeks four and ten — most babies sleep best with their arms in a natural up position, not pinned at the sides. The 1.5 TOG suits a standard 18–20°C UK nursery, the most common range we see in postcodes from N16 to BS8.

  3. iii.

    One palette, three colours.

    Oat, sage, clay. Pick one tone and the kit reads as a wardrobe rather than a stack of unrelated baby clothes. Pick across, and the kit photographs beautifully on a changing mat. Either choice is the right one — the design system is calm enough to absorb it.

A short note from the studio

For the first three months at home.

The first weeks home are not a season — they are a window. The car seat comes in, the visitors leave, the temperature in the bedroom is suddenly a question that needs a daily answer. The First Nights Kit was put together for that exact window: from the day you arrive home, through the early swaddled weeks, until the bodysuit no longer snaps cleanly at the gusset.

It is also the kit we keep packing up for friends. The two pieces we tell new parents to buy first, the ones we hand over wrapped in cotton twine when the baby is born and the gift list has run out. Bundling them at one price means a discount against buying each piece à la carte, but the more honest reason is that, sold separately, the swaddle and the bodysuit get matched together by the parent rather than by us — and we know which way around the swaddle goes.

Returns are open thirty days, sizes can be exchanged unworn, and the keepsake box returns to us — laundered, refilled, passed to the next family.

If The First Nights Kit is for the first three months at home, here is what to reach for as the seasons turn.

In the nursery

Photographed at home, in the quiet hours. The First Nights Kit, worn by the babies who tested it.

  • "Born on the 4th, in the bundle by the 7th. The swaddle survived the first ten weeks — then we slid the sleep bag in without thinking." — ELSA & MARGAUX, N16

  • The cream keepsake box, returned and refilled. Each one finds a second family.

  • "The temperature dipped, the bag did its job. I didn’t get up."

  • Twelve weeks in. Out of the swaddle, into the bag. No new shopping list.

  • Fifty washes in. Cotton softens; the swaddle holds shape.
