Dressing your little one is one of the most exciting parts of parenting — but figuring out the right size? That can feel overwhelming. Kids grow fast, and sizing varies between brands. Here's a simple guide to help you choose the right Pookoo romper size for your child.

Understand Age vs. Size

Clothing sizes are based on average weight and height ranges, not just age. A 2-year-old on the taller side may fit better in a size 3. Always check the brand's size chart before buying.

General Size Guide

  • 12–18 months: 22–27 lbs / 80–86 cm
  • 18–24 months: 27–30 lbs / 86–92 cm
  • Size 2: 30–34 lbs / 92–98 cm
  • Size 3: 34–38 lbs / 98–104 cm
  • Size 4: 38–42 lbs / 104–110 cm
  • Size 5: 42–46 lbs / 110–116 cm

When in Doubt, Size Up

Rompers that are slightly big will still look adorable — and kids grow into them quickly. Sizing down means you may only get a few weeks of wear.

Why Our 2-Way Zipper Makes All the Difference

Pookoo rompers feature a 2-way zipper that works from both the top and the bottom — and parents love it for two big reasons:

  • Easy diaper changes: Unzip from the bottom without fully undressing your baby. No more wrestling with snaps at 2am.
  • Toddler independence: Older kids can zip and unzip themselves from the top, making it easy for them to dress on their own — a big confidence boost for little ones learning to get ready.

100% Organic Cotton Fleece, All-Season Comfort

Our rompers are made from 100% organic cotton fleece — free from harsh chemicals and gentle on your child's sensitive skin. Organic cotton fleece keeps your child comfortable in cooler weather and all season long, with a natural softness that gets even cozier with every wash. Whether it's a crisp fall morning or a chilly winter day, your little one will be warm, happy, and ready to play — the clean, natural way.

Final Tip: Buy for the Season Ahead

If your child is in a size 2 in early fall, sizing up to a 3 means they'll get the full wear out of their cozy organic fleece romper all winter long.
