Can this be normal - please reassure me. She bites towels and woolly clothes, takes a big bite and then pulls it away so she is left with threads in her teeth. She bites her board books and ends up eating the resulting bits of cardboard. She can give me a painful bite through jeans. She's now started on the sofa and no toy is safe. She even seemed happy biting a soapstone carving. We gently say no and move the thing away but it's hard when it's the towel you're drying her with or her coat.
So I'm hoping you will all tell me your dc's did this and it stopped at 12months. Thanks!
