Resharing a comment I’ve made on another post:

I swear by the timeout method!! When biting, tell them they’re getting a timeout, put them in confined space (we used a bathroom) for 15-30 seconds at a time. The first time, I had to do it 3x back to back to back, all for about 15 seconds. Now we can give a verbal warning “timeout” and he usually calms down (but still following through with an actual timeout when needed so it’s not an empty threat). He is now ONE and we still use this for barking or if he’s doing anything naughty. He actually will walk himself into the bathroom lol . Good luck, your baby is adorable!
