I found crib rail covers on Amazon that are just fabric that ties on. He hasn't looked for another place to chew so just covering worked for us!
Thanks everyone! We ordered crib rail covers on amazon and hope those will help. They don’t come until 9/9 though. She may eat her entire rail off by then. Ugh lol
They make a plastic cover you can stick onto the railing. I used this with my daughter when she was younger. We will be getting it for my son soon
