You’d be hard-pressed to find a baby boutique that doesn’t stock organic onesies these days. But the hunt for toddler underthings made with organic cotton requires a bit more sleuthing. Here, a few of the best organic options for Big Kid unmentionables.

1. For sensitive skin: Hanna Andersson’s classic “unders” for girls and boys come in fun patterns and are finished with smooth, flatlock seams that completely cover the elastic; $20 for a pack of three.

2. For the French sophisticate: Petit Bateau’s organic cotton boxers ($26), panties ($12), and chemises ($20) look just like mom’s and dad’s.

3. For classic undies: Under the Nile’s organic cotton training pants ($13) and briefs ($8) for boys and girls are made with a stretchy waistband, so they’re easy to pull up.

4. For parents with a sense of humor: Baby Wit’s organic training pants ($10) sport potty humor jokes like “stinky” and “biohazard” on the tush.

5. For the Plain Jane and Simple Joe: With no frills or loud designs, Ecoland’s simple yet classic underpinnings—camis ($20 for 2), tanks ($20 for 2), hipsters ($15 for 2) and briefs ($17 for 2)—are great for little girls and boys who boycott certain colors and patterns.
