11 month old eating her blanket

Should I be concerned with my 11 month old... She eats her blanket anytime she sees it. Bites little pieces off of it and eats the fluff? Does anyone else's kid do this? It does worry me a little. She is teething with a milar at the moment so I know everything goes into their mouths but it's like she's looking at these fluffy blankets like they're candy 😂😂
