  PUPPAPUPO underwear is designed for quick and easy clothes changes

  A front-opening design that makes changing easy from the newborn stage. Designed for convenience, both the inner and outer fastenings use quick snap buttons. The buttons, except for the crotch snaps, can be adjusted in two sizes as your baby grows. Made with your baby’s comfort in mind, the seams are carefully designed to minimize irritation against delicate skin while ensuring easy dressing. Since babies need frequent outfit changes during infancy, ease of dressing is an important point when choosing baby underwear.

  Soft and fluffy 100% cotton jersey knit fabric

  Baby’s skin is very sensitive and they tend to sweat a lot. Baby underwear is usually made from nearly 100% cotton, but even 100% cotton comes in different types depending on the knitting method. This item uses “jersey knit” fabric, which is breathable and does not easily trap moisture. As it is double-layered jersey knit, it also provides moderate warmth. It is a soft and fluffy warm fabric, perfect for the cooler fall and winter seasons.

  Short underwear features

  The “short underwear” is a shorter-length garment that makes layering easy. Its main role is to absorb sweat, just like adult undershirts. It features a front-opening design and can be adjusted with ties or buttons to fit your baby’s growth. Since it is used almost daily during the newborn stage, it can be worn from birth and is also suitable to be worn under a ceremonial dress when leaving the hospital after delivery.

• 

  Combination underwear features

  The front-opening design and snap closures at the crotch keep the underwear securely in place, even as your baby becomes more active. Designed to help regulate body temperature and prevent the fabric from riding up, it features adjustable ties or buttons for a comfortable fit as your baby grows. Wear it alone or layer it with short underwear depending on the weather.

  Baby underwear Q&A

  Q: How many newborn underwear pieces do I need?
  A: We recommend having 5–6 short underwear pieces, including extras for laundry.
  Q: What's the difference between short underwear and combination underwear?
  A: Start with short underwear as a base layer to absorb sweat, then layer combination underwear over it to keep your baby’s legs and tummy comfortably covered. This is a classic layering style for newborns.
  Q: How long can my baby wear newborn underwear?
  A: Size 50-60 (0-3M) is generally suitable until around 3–4 months, when your baby starts gaining better head control. Once your little one begins rolling over and moving more, we recommend switching to a romper-style underwears, which stays in place better and helps keep the tummy covered.
