As parents how do you feel about biting?

Hi guys I’m not a parent but I have worked in daycares for the past 5 years. How do you guys feel about having your kid home with a bite mark or hear that your kid has bit. Especially as a toddler parent. As a toddler teacher with a 1:7 ratio it’s hard to constantly be on top of kids that are biters. Especially when I’m in a room alone changing diapers. Even though this is completely normal for this age group I understand how frustrating it can be. And I feel like I have become used to seeing it. Is this also happening during play dates? What do you guys think as parents would be a good way to handle this.
