I have a 13 week old and all he wants to do is bite. You can?t even pet him unless he is just worn out without him biting you. It?s not his bite pressure that hurts, it?s his extremely sharp baby teeth. You can?t stand up or take one step without him biting your legs, feet, socks, shoes, or anything he can reach. Redirecting to another toy doesn?t work, he immediately goes back to your skin. Any tips other than just waiting it out until he is done teething?
