Quick answer

Choose a baby bloomer by matching the size to your child's current weight and age, prioritizing a snug but comfortable waistband and easy movement, and selecting a fabric that suits the season and activity.

Why sizing matters more than age

Babies grow at different rates, so age labels are only a starting point. The most reliable way to choose the right size is to measure your child's waist and hips and compare them to the brand's size chart. KicKee bloomers come in sizes that correspond to typical weight ranges, but always check the specific measurements.

A bloomer that's too tight can leave red marks and cause discomfort, while one that's too loose may slip down or bunch up. Look for a fit that's snug enough to stay in place but not so tight that it digs in.

Fabric and season: breathability vs. warmth

The fabric of a bloomer affects both comfort and function. For warm weather, choose a lightweight, breathable material like bamboo that wicks moisture and keeps your baby cool. For cooler months, you might opt for a slightly thicker cotton or layer the bloomer under pants.

KicKee's bloomers are made from a soft, buttery bamboo fabric that feels gentle against the skin and is ideal for everyday wear. This fabric is also easy to move in, making it perfect for active babies who are crawling or walking.

Style and versatility: ruffles, prints, and neutrals

Bloomers come in a range of styles, from solid colors to playful prints. Ruffles add a charming detail that many parents love, but they can also add bulk. If you plan to use bloomers under dresses, a ruffle-free or lightly ruffled style may be more comfortable.

Solid colors like sage green or banana yellow are versatile and can be paired with many tops, while prints like gingham add a fun, seasonal touch. Consider your child's wardrobe and choose a bloomer that can be mixed and matched easily.

Decision rules for choosing a baby bloomer

Measure first: Use a soft measuring tape to measure your baby's waist and hips. Compare these numbers to the size chart provided by the brand, not just the age range. Write down the measurements and keep them handy for future purchases.
Check the waistband: The waistband should be snug but not tight. You should be able to slide two fingers between the waistband and your baby's skin. If it leaves red marks, size up. If between sizes, choose the larger size for a longer wear time.
Consider the activity: For active babies who crawl or walk, choose a bloomer with a flexible fit and breathable fabric. Avoid styles with excessive ruffles that might restrict movement. Test the bloomer by letting your baby move around in it for a few minutes.
Match the season: In warm weather, opt for lightweight, breathable fabrics like bamboo. In cooler months, you can layer bloomers under pants or choose a slightly thicker fabric if available. Keep a few seasonal options in rotation to adapt to temperature changes.
Think about diaper changes: Look for bloomers with easy access for diaper changes, such as a snap closure or a stretchy waistband that can be pulled down quickly. If you prefer quick diaper changes, prioritize styles with snaps over pull-on designs.
