Your body changes every few weeks during pregnancy, and what felt comfortable in month two can feel tight, hot or awkward by month seven. In Singapore's heat, sleepwear does more work than usual: it has to stay cool, stretch with you and, after the birth, make night feeds easy. This guide walks through what to look for in maternity and nursing pyjamas at each stage, so you buy fewer pieces that last longer.
Why maternity pyjamas matter more in Singapore
Pregnancy raises your resting body temperature and blood volume, so many expectant mothers run warmer at night. Add Singapore's year-round humidity and night sweats become common. The single most useful thing your sleepwear can do is breathe and manage moisture. Look for natural, plant-based fibres such as Tencel lyocell, bamboo or a bamboo-linen blend, which absorb moisture and dry faster than polyester or heavy cotton. Selenightco's fabrics are all natural fibres with no polyester; you can read how they are made on our Our Fabrics page.
First trimester (weeks 1–13): comfort for tiredness and tenderness
Your bump may not show yet, but fatigue, nausea and breast tenderness often do. You probably don't need maternity-specific pieces yet. Instead:
- Choose soft, smooth fabric against tender skin. Avoid scratchy seams, lace and stiff trims.
- Go relaxed, not tight. A relaxed-fit PJ set in your usual size is often enough for now.
- Prioritise breathability. Many women find they overheat early in pregnancy. Short sleeves or a camisole set help on hot nights.
Second trimester (weeks 14–27): room to grow
This is when most women start to need more room through the waist and chest. What to look for:
- Adjustable or soft elastic waistbands that sit comfortably under or over the bump without digging in. Drawstrings are useful because you can loosen them week by week.
- Button-front tops, which give extra room across the chest now and double as nursing tops later.
- Night dresses as an alternative to sets: there's no waistband at all, which many women find the most comfortable option in the third trimester too. See our dresses.
- Sizing up one size in relaxed-fit pieces rather than buying maternity-only cuts. Check the chest and hip measurements on our size guide before you choose.
Third trimester (weeks 28–40): ease, cooling and hospital-readiness
Sleep gets harder as the bump grows, and comfort becomes the priority. Look for:
- Longer tops that cover the bump fully, so you're not tugging at the hem all night.
- Low-slung or very soft waistbands, or a sleep dress with no waistband.
- Cooling, moisture-wicking fabric. Third-trimester night sweats are common, and you will be changing positions often.
- Something you are happy to wear in hospital. A dark or patterned button-front set is practical for the delivery ward and for visitors. We cover what to pack in our hospital bag and confinement guide.
After birth: what makes a good nursing pyjama
Once the baby arrives, the requirements shift again. Nursing pyjamas need to give quick, one-handed access in the dark. The features that matter most:
- Full button-front tops, the simplest and most reliable nursing access.
- Stretchy, soft fabric that is gentle on sensitive skin and survives frequent washing.
- Easy-care materials. Expect milk leaks and spit-up, so choose pieces you can wash often on a gentle cycle.
- Two or three sets in rotation, so you always have a clean one while others are drying.

Fabric quick guide for pregnancy and nursing
- Tencel lyocell: smooth, cool to the touch and very absorbent. A good choice for night sweats.
- Bamboo: soft with natural stretch and breathability. Comfortable as your shape changes.
- Bamboo-linen: airier and more textured; ideal for the hottest nights. Browse the bamboo-linen collection.
- Avoid polyester and heavy synthetics, which trap heat and moisture against the skin.
How many sets do you need?
A practical capsule for pregnancy through the newborn months is three to four pieces: two button-front PJ sets for nursing, one night dress for the late third trimester, and one lighter short-sleeve or shorts set for the hottest nights. Button-front sets carry you all the way from the second trimester to nursing, so they offer the best value per wear. Browse our PJ sets to start.
Frequently asked questions
Do I need special maternity pyjamas?
Not always. Many women manage the whole pregnancy in relaxed-fit sleepwear one size up, plus a sleep dress for the final weeks. Maternity-specific cuts are helpful mainly if you prefer a fitted look.
When should I buy nursing pyjamas?
Around weeks 30–34, so you can pack them in your hospital bag. Button-front sets bought in the second trimester often work for nursing too.
What size should I buy?
Measure your chest, waist and hips and compare them with our size guide. Our pieces are cut with a relaxed fit, so many women size up once rather than repeatedly. If you're unsure, email hello@selenightco.com.
Pregnancy and the newborn months are demanding enough without fighting your sleepwear. Choose breathable natural fabrics, adjustable waists and button fronts, and you'll have pyjamas that work from the first trimester to the first year. Shop Selenightco PJ sets.
