petitmain This is a cooling sheet for baby carriers. It was used a few times last year and has been stored at home. Comes with a cold pack. Please let me know in the comments if you don't need it. You can also use it on a stroller by tying both straps to the stroller's handle. The floral design is very cute. Size: 17cm x 29cm This baby carrier sheet has cooling features that are useful on hot days. The fabric, made with contact cooling, mesh material, and soft batting, gently touches the baby's back, where body temperature tends to rise. The assorted designs with cute patterns are also perfect as a gift. It can be used from around 3 months of age.
