The Girls' Onesie Pajama Tips and Advice

  • Getting the size of the onesie pajamas right is key, otherwise, your child will have a hard time wearing it. Measuring her height accurately is important, and be sure to use the sizing chart. If you get a onesie pajama in the wrong size, she will not be able to wear it comfortably.
  • If you want to up the coziness of the onesie pajamas, go with one that has a hood attached. This is the perfect way to stay warm and snug, especially in cold weather.
  • Going to the bathroom with a onesie on can be challenging. However, you can find a onesie pajama that has a convenient back flap. This style is key if you plan on wearing the onesie regularly for long stretches of time.
  • Zippers or buttons? It’s a personal preference. Zippers are faster to open and close, while buttons can take a while, especially if there are many of them. Zippers can also be finicky and break, and are hard to replace. It’s relatively easier to re-stitch on a missing button.
