What should a 2-month-old wear?
4 min read
Quick answer
A 2-month-old should wear one more layer than you, as the NHS suggests. On a mild day that is a vest and light sleepsuit; on a cool day add a cardigan, hat and pramsuit; on a hot day, one cotton layer and shade. In a carrier, go a layer lighter, and check the back of their neck.
- Same warmth rules as a newborn
- Carrier: your body counts as a layer
- Under 6 months: shade, not sunscreen
- Sleep: room thermometer and TOG, not the forecast
What changes at 2 months
Temperature rules stay the same at 2 months. Many babies are more awake and alert now and spend longer out on walks, in a pram or a carrier. Longer outings mean the weather can change while you are out, so pack one spare thin layer and a hat for the season.
Your baby is still under 6 months, so the NHS advice to keep them out of direct sunlight, and not to use sunscreen, still applies. Shade and clothing do the work.
What should a 2-month-old wear outside?
Use the outdoor temperature to decide. As a guide:
- 10–14°C (50–57°F): vest, sleepsuit, warm cardigan, pramsuit, hat and mittens
- 15–18°C (59–64°F): vest, sleepsuit and a cardigan or light jacket
- 19–21°C (66–70°F): vest and light sleepsuit, thin cardigan to hand
- 22–23°C (72–73°F): short-sleeved vest and light trousers or a romper, sun hat
- 24–26°C (75–79°F): single layer of lightweight cotton, wide-brimmed hat, shade
- 27–30°C (81–86°F): one thin cotton vest or romper, wide-brimmed hat, full shade
What should a 2-month-old wear to sleep?
For naps and nights, dress for the room. NHS advice is a room of about 16–20°C, your baby on their back on a firm, flat mattress, with no loose blankets. As a guide:
- under 16°C (under 61°F): a vest plus a long-sleeved sleepsuit under a warm (2.5 to 3.5 TOG) sleeping bag
- 16–19°C (61–66°F): a long-sleeved cotton sleepsuit under a 2.5 TOG sleeping bag
- 20–23°C (68–73°F): a cotton sleepsuit (or long-sleeved vest) under a 1.0 TOG sleeping bag
- 24–26°C (75–79°F): a short-sleeved cotton vest under a 0.5 TOG sleeping bag
- 27°C+ (81°F+): a short-sleeved cotton vest, alone or under a 0.2 TOG sleeping bag
How to check your 2-month-old is not too hot or cold
Feel the back of your baby's neck, their chest or their tummy. Warm and dry means they are dressed right. Sweaty or hot means take off a layer of clothing or bedding. Cool hands and feet on their own are normal, so do not add layers just because fingers or toes feel cold.
Babies in a carrier, or in a pram with the hood up, can warm up faster than you notice. Check the back of the neck when you stop walking. If it is damp, take a layer off. If it is cool, add the spare.
Carriers, prams and car journeys at 2 months
In a carrier, your body warmth acts as a layer, so a 2-month-old usually needs one layer less than in the pram. Keep their face clear and visible, and add a hat when it is cold or sunny.
In the pram, use a clip-on parasol or sunshade for shade, and never cover the pram with a muslin or blanket (NHS). Once you step into a warm car, bus or train, remove hats and extra layers straight away, as the NHS advises, even if your baby wakes.
This is general dressing guidance, not medical advice. If you are worried your baby is unwell, call NHS 111 or your GP. In an emergency, call 999 or your local emergency number.

Questions parents ask
Should I dress my 2-month-old warmer because they are small?
Not automatically. Dress for the air temperature, using the NHS rule of one more layer than you, then check the back of the neck. Young babies struggle to keep their body temperature steady, which is why checking matters, but extra layers can lead to overheating.
What should a 2-month-old wear in a carrier?
Usually one layer less than in the pram, because your body warmth counts. On a mild day, a vest and sleepsuit is often enough. On a cold day, add a cardigan, hat and socks, and zip your coat or a carrier cover around you both. Check their neck when you stop.
Can a 2-month-old wear sunscreen?
The NHS does not recommend sunscreen for babies under 6 months and advises keeping them out of direct sunlight. Use shade, the pram hood, a clip-on sunshade, a wide-brimmed hat and light clothes that cover the skin. The AAP says a little sunscreen on small areas such as the face is fine only if shade and clothing are not possible.
What should a 2-month-old wear to sleep at 20°C?
At 20°C, a cotton sleepsuit or long-sleeved vest inside a 1.0 TOG sleeping bag is the usual choice. 20°C is the top of the NHS ideal range of 16–20°C, so avoid adding a vest under the sleepsuit unless your baby feels cool on the neck or chest.
