How do I get my 3 year old daughter to stop sucking on her lip?

hmmm... put lemon on there when she does it and that should probably get her to stop, im sure there are more effective ways but im guessing this should work? ive been wrong before though but its worth a try, good luck hope ihelped a little if anythingg

i dont think that her sucking her lip should be a problem little kids uaually have weird "habits" that usually go away after a while... but if you are really worried about you should put lemon juice (as stated above) or something that she doesnt like the taste of...
