Some babies do it and some don't. What are we talking about? Babies that chew and bite on the crib guard. If your child is into it, you may have looked for something secure and safe to cover and protect the guard rail. We found this fabric crib rail guard protector by Etsy seller New England Quilter. The guard is made with flannel fabric and quilted on the diagonal. New England Quilter adds two layers of batting for extra softness. Each has 5 buttons to secure the guard to the crib rail. As far as rail guard protectors go, this one is nice looking. You can even contact her directly for a custom order.
