When they bite, stop the feed and say no. Give then a teether and wait for a bit before feeding again. Try and give teething medication before a feed too.....x
I won’t lie. The first time it happened, I screamed bloody murder because it felt like a needle/puppy teeth/a knife all in one and I think it scared him.
When he’s actually eating, he doesn’t bite. I’d maybe take that as he actually isn’t hungry… try again in 5-10 minutes.
