Organic cotton newborn gown and bear hat set, clay, 0–6m

Yes — all our cotton sleepwear is made for sleeping in. UK safer-sleep guidance from The Lullaby Trust is about what's loose in the cot (blankets, toys, pillows), not what your baby's wearing. A correctly sized sleepsuit, gown, or pyjama set is the safest base layer for nighttime.

Ribbed has visible vertical lines, plenty of stretch, and softens with every wash — the most versatile for year-round wear. Interlock is smoother and denser, slightly warmer, and holds its shape through repeated washes. Honeycomb mesh has an open weave that's more breathable than standard cotton — best for warmer rooms and summer nights.

Our sleepsuits run true to UK age sizing. Newborn for the first few weeks, 0–3m up to about 14lbs, 3–6m up to about 17lbs. If you're between sizes, size up — babies grow into them faster than you'd expect, and a roomier fit is more comfortable for sleep than a tight one. Detailed size charts are on every product page.

Two-way zips open from the top or the bottom, so a nappy change at 3am doesn't mean stripping the whole sleepsuit off and starting over. The collar cover sits over the zip pull at the neck, keeping it away from your baby's skin. Small detail, big difference when you're doing the fifth change of the night.

Newborn gowns are useful for the first few weeks, when night changes happen most often. The knotted hem loosens with a single pull, so you can access the nappy area without managing zips or snaps. After the first month or so, most parents move to sleepsuits with two-way zips — but those first weeks are easier with a gown.
