I've popped her on the butt when she's bitten me good. Usually I try to stay ahead of her and recognise when she's about to bite, say "no biting" and then redirect her. Its worse when she's teething but it's also an age thing :/ they have to grow out of it
Well I'm glad to know I'm not the only one and that I did the right thing
I popped my daughter (not hard) but enough to get her attention and told her its not ok to bite.
My son is 9 months old and bites I normally will tell him no don't bite and if I have to telling him again I tell him not don't bite if you do it again you get your mouth smacked normally I only have to tell him twice
