How would u discipline your one year old for biting?

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

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 mines also not 2 hard just enough 2 catch her attention

I popped my daughter (not hard) but enough to get her attention and told her its not ok to bite.

I tap my daughter's and tell her no for doing that
