Hospital bag lists exist in every pregnancy guide, parenting app, and midwifery leaflet. Most of them are too long.
The first days after birth are not a time for outfit variety. They are a time for simplicity — easy-access clothing for feeding and examinations, soft materials that won't irritate days-old skin, and enough pieces to cover the unexpected without overpacking.
This is a practical guide to the clothing that actually matters, and why.
How Many Pieces to Pack
Newborns have limited control over temperature regulation and feed frequently, which means clothing changes happen regularly. For a typical two to three day hospital stay, pack:
- 3–4 newborn-size sleepsuits or babygrows
- 2–3 short-sleeve bodysuits (worn underneath for temperature layering)
- 2 hats
- 1–2 cardigans or lightweight wraps for temperature variation
- 1 going-home outfit (slightly warmer or more considered than the hospital basics)
This covers regular changes, unexpected spills, and the going-home moment without requiring a full suitcase of clothing options that won't be used.
Sizing: The Most Common Mistake
Newborn-size clothing is sized for babies up to approximately 3.5kg at birth. A significant proportion of babies are born at or above this weight and will not fit newborn sizing at all, or will outgrow it within days.
Pack both newborn and 0–3 month sizes if you don't know your baby's birth weight in advance. Adjust after the birth. Returning unused items in 0–3 month sizing is easier than scrambling for larger pieces in the first days home.
For the going-home outfit specifically: 0–3 months fits most newborns and will still be usable in the weeks after discharge — unlike newborn sizing, which may already be redundant.
What Materials Work in the First Days
Newborn skin is significantly more sensitive than adult skin and reacts to materials that most people wouldn't notice. The first days after birth are not the time to test unknown fabrics.
Organic cotton — the right base material for newborn clothing. Soft, breathable, and free from synthetic pesticide residues when GOTS certified. This is what should be against days-old skin.
Merino wool — appropriate for the hat and any outer layer. Temperature-regulating and naturally soft. High-quality merino does not itch. Not appropriate for the base layer closest to skin in the very early days — some newborns react to any wool, however fine.
Synthetics and blends with significant polyester content — avoid for the newborn period. Synthetic fibres don't breathe and can irritate sensitive skin. There is no practical benefit to synthetic content in a newborn garment that justifies the trade-off.
Certification: OEKO-TEX Standard 100 on the finished garment tests for harmful substances including dyes and processing chemicals. For newborn clothing, this is not a premium — it is a baseline.
Construction Details That Matter
Envelope necklines — newborn necks are not designed to assist with dressing. An envelope neckline (the folded-over shoulder that stretches open) makes dressing and undressing possible without stress for baby or parent. Tight, fixed-width necklines are a source of frustration in the first days.
Flat inner seams — raised inner seams irritate newborn skin. The first days of life involve enough sensory adjustment without added friction from clothing construction.
Simple fastenings — metal snaps that open at the crotch are the practical standard. Press studs down the front body allow full access for the examinations and skin-to-skin contact that happen constantly in the first days.
The Going-Home Outfit
The going-home outfit receives more planning attention than almost anything else in the hospital bag and matters less in practical terms than the basics. One well-made piece in 0–3 months organic cotton, slightly more considered than a standard babygrow, is sufficient.
It will be photographed extensively. It should be comfortable, appropriate for the season, and sized so it is still usable in the weeks after birth.
