Baby burms can be a touch nippy when get them. I found that with regular handling they will calm down relatively quickly. I had quite a few baby's over the years and I can't think of a single one that didn't tag me at least once. I can also say that I never owned one that just wouldn't calm down. Hook training is a must though. I did have a few that were a little cage aggressive over the years. Just be patient and keep on him, and you should be fine.
