X netherland mini lop male 2 months old.he is licking then biting us or our trainers should I be worried?

New rabbit and kept indoors.he is out all time we are in, he has cage. Dont want him to be a biter. he has a wooden toy to chew but seems to ignore it. Am I panicking and he is still a baby? My daughter(10) adores him but he hasnt bit her yet.If he does she will be scared of him.Any ideas please. First rabbit. x
