For sensitive skin,Β organic cottonΒ is typically the best choice for toddler pillowcases.
Why organic cotton wins for sensitive skin:
Chemical-free: No harsh dyes, pesticides, or synthetic treatments
Breathable: Prevents overheating and irritation
Gets softer: Becomes gentler with washing, unlike synthetic materials
OEKO-TEX certified: Tested to be free from harmful substances
Bamboo-derived fabrics are the second-best choice as they’re naturally antimicrobial and hypoallergenic, though some children with very sensitive skin may still react to the processing chemicals used in bamboo-to-fabric conversion.
