#1 If your little one has grown out of their pjs, simply cut the pajama feet off below the zipper. Voila, those pj's should fit for another 6 months. #2 If your little one likes to take their diaper off (and sometimes leave you with a HORRIBLE mess). Purchase full-zip pjs without feet and put them on backwards (Hannah Anderson has them for sale). Or cut the feet off the pjs and put them on backwards. Most children (and I say, most, not all) will give up trying to get the pjs off. Voila, your child and their messy diaper will stay safely tucked into their pjs.
