I don't know Bamm or Josh enough to answer that question really :/ but I would go with your gut.
Yes, he's your husband, but if it's an issue of Bamm's safety and/or you think he might bite someone.. I would be pretty wary as well.
Do you think Bamm would/could bite someone/are they going somewhere where people could show up? That would be my only real issue in a situation like this. Because regardless of you being there or not, if he bites someone and that person reports it got forbid..that could be a big issue.
