You can use a hook to get him out if you like. That seems to help with my yearling JCP.

Other than that, the best thing you can do is keep the sessions short in the beginning and whatever you do, DON'T put him back until he's calm. If he's biting you and trying to get away you want to keep working with him until he stops. If you don't, he'll learn that by acting up and biting he can get let go.

Be consistent and also just give him time. Baby carpets can be nippy but they almost all settle down after a year or so of age.

Do you have any pictures of the little guy?
