My 7 month old bites me when she feeds help!

My daughter bites me occasionally, I know she latches good and people say she can't bite it properly latched which I know, but when she plays around she bites really hard what can I do to stop that? I have tapped(lightly) her on the nose and pulled my nipple put and said no or ouch or no biteing or stop feeding for a short time then tried again. Help any advice would be grate@
