100% organic cotton  baby pajamas have a diaper area to keep the child comfortable while sitting around or crawling. These are available in natural and brown colors and are made out of very soft Interlock fabric. This helps keep baby's feet protected in any season, especially when they are crawling around. Since these are made out of Organic Cotton, they do not have any harmful effects on the child's sensitive skin and can be worn all day long. We use Azo free, heavy metal free dyes because we care.
