Learn how to choose the right Flying Squirrel pajama size for your toddler. Get fit tips, size chart guidance, and know when to size up or down.

Quick Answer

Choose a Flying Squirrel pajama size based on your toddler's height and current weight, not age. The fit should be loose with room to grow, but not so big that fabric bunches or becomes a tripping hazard. If your toddler is between sizes, size up for longer use, but check that the cuffs stay snug at wrists and ankles.

Finding the right size for your toddler's sleep sack can feel like a guessing game, especially when they are growing quickly. The Flying Squirrel pajama from Blooming Baby is designed to be a wearable blanket that lasts from 12 months to 5 years, but getting the fit right is key to comfort and safety.

This guide will walk you through how the Flying Squirrel should fit, how to use the size chart, and when to size up or down. We'll also share practical tips for making the right choice, so your little one can sleep soundly all night.

How Should a Flying Squirrel Pajama Fit?

The Flying Squirrel pajama is meant to be loose and roomy, giving your toddler plenty of space to move and grow. Unlike tight-fitting pajamas, the loose fit allows for natural movement during sleep. The ribbed cuffs at the wrists and ankles are designed to prevent the fabric from hiking up, so the sleeper stays in place.

When you put the pajama on, check that there is extra fabric around the torso and legs. Your toddler should be able to stretch, roll, and kick freely. The cuffs should sit snugly but not tightly, and the fabric should not bunch up under their back or around their neck. If the sleeves or legs are too long and the cuffs are not snug, the fit is too big.

  • Check that the cuffs are snug but not tight; you should be able to slide a finger between the cuff and your toddler's wrist or ankle.
  • Ensure the fabric does not bunch under the chin or around the neck; the neck opening should be comfortable and not too loose.

Using the Size Chart: Height and Weight Matter

The Flying Squirrel pajama is available in sizes that correspond to your toddler's height and weight, not just age. Always measure your child and compare their height and weight to the size chart on the product page. Age is a helpful starting point, but every child grows at their own pace.

If your toddler is between sizes, consider how much room they have in the current size. If the cuffs are already snug and the fabric is tight across the chest or hips, it's time to size up. If there is more than a few inches of extra fabric at the ends of the sleeves and legs, the current size may be too big.

  • Measure your toddler's height and weight before ordering, and check the size chart for the specific product, as sizes may vary slightly between fabrics.
  • When in doubt, size up for longer use, but verify the cuffs are snug enough to prevent the fabric from riding up.

Sizing Up vs. Sizing Down: Trade-Offs

Sizing up gives your toddler more room to grow, which can extend the life of the pajama. However, a size too big may have excess fabric that can bunch up, making it uncomfortable or even a safety hazard if it covers the face. The loose fit is intentional, but there is a limit.

Sizing down ensures a snugger, more secure fit, but you may need to replace the pajama sooner as your toddler grows. A size too small can restrict movement and be uncomfortable. The key is to find a balance: the pajama should be loose enough for comfort but not so big that fabric pools or cuffs slip.

If your toddler is between sizes, size up only if the cuffs are snug and the fabric does not overwhelm their frame. If the current size is snug but not tight, you can likely keep using it for a bit longer.

  • Check the fit around the chest and hips; the fabric should not pull or feel tight when your toddler moves.
  • If the sleeves or legs are so long that the cuffs do not stay in place, the size is too big.

Fabric and Fit: Does It Change How It Fits?

The Flying Squirrel pajama comes in different fabrics, including a breathable polyester blend and a fleece version. The fabric can affect how the pajama drapes and feels. The fleece version is warmer and may feel slightly more snug initially, but it should still have the same loose fit. The lightweight version is more breathable and may feel more roomy.

When choosing a fabric, consider the season and your toddler's sleep environment. The fit should be the same regardless of fabric, but you may need to adjust your expectations for warmth. Always follow safe sleep guidelines and avoid overheating.

  • For warmer months, choose a lightweight fabric; for colder months, consider fleece.
  • Remember that the fit should be consistent across fabrics, but the feel may differ.

Quick Fit Decision Rules

  • If your toddler is between sizes: Size up if the cuffs are snug and the fabric is not overwhelming. This gives room to grow and extends the life of the pajama. Check that the cuffs stay in place and the fabric does not bunch excessively.
  • If the current size is snug but not tight: You can keep using it for a while longer, but monitor for signs of tightness, such as red marks on the skin or difficulty moving. If the fit feels restrictive, it's time to size up.
  • If the pajama is too big: Excess fabric can bunch up and become uncomfortable or unsafe. If the cuffs are not snug and the sleeves or legs are too long, choose a smaller size. The pajama should be loose, but not so big that fabric pools or covers the face.
