My beaver. . . I mean baby, likes to chew into the wood of her crib. The straight sides have a plastic guard over it; however the curved head and end sides are exposed. When she is quiet in her room (or perhaps when light from the full moon pours through her bedroom window, transforming her into a beaver-by) she must be staning at the end of her crib and lick the crib until she finds a spot that she likes to bite into. OVER AND OVER AND OVER AND OVER AND OVER again. I first noticed small bite marks about 3 or 4 months but I didn't put much thought into this because I thought she would grow out of this quickly. I mean, how is this appealing. But I noticed yesterday that the biting has not stopped and it is clear that she is licking the varnish off the rest of the edge. Can anyone suggest something here. I can't think of something that would be flexible to cover the edge the right way, but not be bite-able. Can you?
