Hi & Welcome,
We have Darby, now 13 weeks who we've had from 8 weeks & Dexter, now 16 weeks who we've had from 14 weeks.
Both pups learnt bite inhibition very quickly. The whole family reacted to play bites in a way that made them think they were hurting, even if they weren't, by giving a sharp intake of breath or saying 'ouch'. The theory is that they soon come to the conclusion that humans are soft, so they'd better be careful with us & if they're not, then the fun game comes to an abrupt end.
Worked well for us with both of them. Good luck!
