18 month old biting nails

[shinyshilling]

My DD is 18 months and has started biting her nails which her Dad does all the time. Will this be learned behaviour or might she be doing it becuase her back teeth are coming in? Should I try and ignore this, sit it out or act upon it now to stop it becoming a problem?

my kids are 5 and 2 and unfortunately they both do it so do i oops!! i have tried stopping them but the more attetion you draw to it the more they do it u could try distracting when shes doing it not sure what else to suggest
