I've looked online to find out how normal it is for a infant to chew away at their hand & can't find much info. Latley Grace has been knawing like crazy & I kept thinking maye she is hungry but she woula have to be hungry all day because she does this almost all day. I read where it's a soothing thing but then when reading more it may be a teething thing due to her drooling now too. Has anyone experienced this?
