There’s a reason onesie pajamas gained popularity in the ’90s and still remain a much-desired item today. They are comfortable, warm and promote a sense of rest and relaxation. If you have small children at home, these onesies can be used as daily loungewear or as practical sleepwear.

You’ll need to consider the age of the child you’re buying the kids’ onesie pajamas for when you begin to shop around. Infants and toddlers do best with footie-style pajamas that are more snug to their bodies. As your baby begins to head toward taking his or her first step, you’ll want to go with footie pajamas that have non-slip grips on the soles of the feet. Older children may prefer onesie pajamas with ribbed ankle cuffs over footie pajamas.

Check that the material used to make the kids’ onesie pajamas isn’t irritating to the skin. A premium 100% cotton is always a good choice, as is a soft polyester. If your child has sensitive skin, look for pajamas that are also tagless.

Consider the style of the pajamas last. Are you looking for a solid color or a simple print? Perhaps your daughter has a love of all things unicorn? In that case, a pair of kids’ onesie pajamas with a horn and a tail may be your best bet. There are also character pajamas that double as Halloween costumes. You’ll find sharks, bears, dinosaurs and even a cyclops are readily available.

DWYM Fun Fact

Did you know there’s actually a Guinness World Record for the largest gathering of people wearing one-piece pajamas in a single venue? The feat took place on Sept. 20, 2015, in Shantou, Guangdong, China. There were a total of 1,879 participants.

According to Record Setter, another record was set by Charlie Tamayo at the Victory Gymnastics Academy in San Diego, California. On Sept. 21, 2013, Charlie stuffed 10 eight-inch foam cubes into his onesie pajamas and then successfully completed a series of tough gymnastics moves.

The Kids' Onesie Pajama Tips and Advice

  • Always check the product care label on the kids’ onesie pajamas before you clean them for the first time. Most are machine washable, but only on the cold water setting with like colors.
  • You’ll need your child’s height, weight, chest and waist measurements in order to consult with the specific manufacturer’s sizing chart. While your child may wear a 4T in one brand, he may be classified as a 5T in another.
  • For safety when purchasing kids’ onesie pajamas for younger children, you need to make sure the pajamas are either naturally flame resistant or that they provide a snug fit.
  • Pajamas that are available in sizes for both children and adults can make great Christmas gifts for families who enjoy dressing alike on Christmas Eve. Some companies even extend their sizes for the canine in your family.
  • When comparing prices for kids’ onesie pajamas, you’ll find multipacks are often cheaper. For example, you’ll pay the same price for the Lazy One Flapjacks Matching Onesie Pajamas as you will for the Simple Joys by Carter’s Snug Fit Kids’ Footed Onesie Cotton Pajamas, 3-Pack, which contains three sets of pajamas.
