UK weather can change quickly, so flexible layers are more useful than one fixed outfit formula. NHS guidance suggests dressing a newborn in one more layer than an adult would wear in the same conditions, then checking the baby’s chest or back and adjusting.
Spring and autumn
A vest and babygrow are a flexible starting point, with a cardigan or light outdoor layer available. Choose pieces that are easy to remove as temperatures rise.
Summer
In warm conditions, a short-sleeved vest may be enough. Keep babies out of direct sun and use shade rather than covering a pram with a blanket, which can trap heat. Remove hats indoors.
Winter
Use several light layers rather than one overly heavy garment. A vest, babygrow and suitable outer layer can be adjusted easily. Remove outdoor hats and heavy layers in warm shops, homes and vehicles.
Sleep and temperature
For sleep, follow current safer-sleep guidance and sleeping-bag tog instructions. The Lullaby Trust recommends 16–20°C. Browse personalised baby vests, baby grows and the newborn range. Read NHS guidance and Lullaby Trust advice.
