Burt's Bees Baby
A budget-friendly way to get GOTS organic cotton on a toddler: the boys' briefs have a 100% organic cotton body, though the girls' styles are 95% cotton / 5% spandex. The synthetic elements are a covered recycled-polyester elastic waistband and the printed patterns (the print chemistry isn't disclosed), which put it at minimal-contact. Good value and genuinely organic cotton, just not a zero-plastic garment.
