How to Dress Your Baby for Autumn: Warmer Days, Chilly Nights
Autumn is that in-between season: mild sunshine by day, a definite chill after dark. Dressing your baby is all about gentle layering, breathable fabrics, and easy add/remove pieces so they stay comfortable as temperatures shift.
The golden rules of autumn dressing
- Layer, don’t bulk. Thin, breathable layers trap warm air better than one thick layer — and are easy to remove if baby gets too warm.
- Choose natural fibres. Pima cotton next to skin; cashmere or merino as a lightweight warmer; cotton or cashmere blankets for on-the-go.
- Watch for overheating. A clammy neck or flushed cheeks = too warm. Cool hands and feet on their own aren’t a reliable sign of being cold.
- One more layer than you. A good quick check for most outings and naps.

Fabrics that work (and why)
- Pima cotton (base layer): Ultra-soft, breathable, gentle on newborn skin — ideal for bodysuits and babygrows.
- Cashmere or merino (mid layer): Warmth without weight; regulates temperature beautifully in changeable weather.
- Knit hats & booties (extras): Help minimise heat loss when you step outdoors.

Daytime dressing (in and out of the house)
- At home: Pima cotton babygrow + light knit cardigan. Keep a soft blanket nearby for feeds or naps.
- Stepping out: Add a knit layer (cardigan or light jumper), a hat, and a blanket over the pram or carrier.
- Pram essentials: Muslin for shade, blanket for chill, spare bodysuit for spills.

Blue Almonds edits:
- Our Heritage Pima cotton pieces (with the rocking horse motif) make perfect base layers.
- Cashmere knits add lightweight warmth without bulk.
- A soft stroller blanket doubles as a pram cover on breezy afternoons.
Night-time: what should baby wear to sleep in autumn?
- Use a long-sleeve cotton bodysuit or Pima babygrow as the base.
- Pair with a season-appropriate sleep bag (check the TOG guidance on your bag and the room temperature).
- Typical autumn UK rooms (about 18–20°C) often suit a 1.0–2.0 TOG sleep bag with a single cotton layer underneath. Always follow the sleep bag’s own guidance.
(If you use blankets at night, keep the cot clear, and tuck blankets firmly at chest height. Follow safe-sleep guidance.)
What to keep in your nappy bag (autumn edition)
- Spare bodysuit and babygrow (pima cotton).
- Light knit layer (cardigan/jumper).
- Soft blanket (pram, feeds, chill).
- Hat (evening chill sneaks up).
- Muslin (shade, spills, comfort).

Sizing & care
- Size with growth in mind (but avoid garments so big they bunch around the face).
- Wash gently: pima on cool; cashmere with a delicate detergent; reshape knits and dry flat to keep them beautiful longer.
