What the AI looks for in Baby Boys' Bloomers, Diaper Covers & Underwear

Fit over the diaper you use
Size by the baby's weight and size up one if you use bulky cloth or overnight diapers Covers sized for a slim disposable will bind or gap over thicker diapers.
Leg and waist elastic
Elastic should be fully fabric-encased, with no exposed rubber at the leg openings Exposed or tight elastic leaves red marks on thighs and rubs during crawling.
Fabric
Breathable cotton or cotton-rich knit, not polyester The cover adds a layer over an already warm diaper area, so breathability helps limit heat rash.
Waterproof or decorative
Check whether the product is a fashion cover or a PUL/wool cloth-diaper cover The two look similar but only cloth-diaper covers are designed to contain wetness.

Brands that matter

  • Gerber: Inexpensive cotton multipacks of covers and basics.
  • Simple Joys by Carter's: Basics multipacks, often sold as bloomers paired with tops.
  • Burt's Bees Baby: Organic cotton basics, a pricier option.
  • Hudson Baby: Budget multipacks of baby basics in many prints.

What to avoid

  • Covers with exposed elastic or scratchy lace or trims at the leg openings
  • Using a fashion diaper cover as a leak barrier over cloth diapers
  • Buying newborn sizes in bulk, since babies outgrow them within weeks

Questions

Are diaper covers waterproof?

Fashion diaper covers and bloomers are not waterproof. Waterproof covers for cloth diapering are a separate product, usually made of PUL or wool.

Baby Boys' Bloomers

Bloomers are diaper covers by another name: the same rules apply, so choose soft cotton with fully encased elastic, sized to fit over the diaper, and do not expect them to be waterproof.
