This is a neck support sheet for baby carriers, designed to prevent a baby's head from flopping forward when their neck isn't fully stable. It's designed like a belt cover, so you can attach it in the same way you would attach a drool bib. This also functions as a drool bib, which is great for babies who tend to chew on the straps. It's only used for a short period, from when the baby can be held upright until their neck is fully stable. I bought it new and washed it once before using it. There's a little bit of dirt, but it might come out with washing. I'll give it to you as is, so please wash it before using. You can remove the cardboard insert and wash the cover only.
