Colored Organics Organic Cotton 12-18 Month Bodysuits FAQs

Most babies fit 12-18M between 22-27 lbs. If your baby is at the upper end of the weight range or is a long sleeper, size up to the next range. 12-18 Months is our standard sizing for babies 12 to 18 months old.
Yes. Wash in cool water with a gentle, fragrance-free detergent. Tumble dry on low or line dry to preserve the organic cotton softness and prevent shrinking.
Our organic cotton is grown without synthetic pesticides or harmful chemicals. It is naturally hypoallergenic, softer with each wash, and gentler on sensitive newborn skin than conventional cotton.
For babies 12 to 18 months old we recommend 5-7 bodysuits in rotation. Babies go through changes often in the first year, so having enough to last between laundry days makes life easier.
