I think tapping on mouth is way different then smacking or biting back. My 11 month old only bites my nipples right now and I'll pull him off my boob and put my finger to cover his mouth and say no biting firmly. He has gotten it after a few times of doing that. I would imagine that would be the same thing I would do with aggressive biting. Probably pull my kid away from the situation and the other kids. Get down to their level and just lightly touch their mouth and say no biting firmly. explain what they did and the consequence. I may give a 30 second time out too.I know they are young but it sets up for good discplin techniques down the road. But I would try to find the triggers for biting. Like is it stressful or too many kids. Is it directed at one kid and why. What is the trigger for the behavior and see if you can correct that. Not to say the behavior doesn't need to be corrected to but its a reaction to something.
