Ds is 16mo and is a biter nobody is safe! My 2 older dc never bit once so I've no idea how to deal with it.
Ds was biten himself by another child a couple months ago at a soft play she made a beer line for him and literally tried to take a chunk out of his arm it was so bad he had teeth imprints on his arm for several days. I'm not sure it's linked could be a coincidence that he started to bite himself a few weeks later.
He thinks it's really funny when he's trying to bite, I say no sternly and move him away but not a clue what else to do I think he's too young to understand
