S.P.
Well, my advice is to sit down together and talk about something you BOTH agree on and stick to it whether its the corner or taking away a favorite toy...you also got to remember you are in the terrible two's which is a really fun time but also a big time to start setting the ground rules. I watch a two year old and she is very good most of the time but she still has her crazy time and when she doesn't listen I put her in the corner it works because she will cry and feel bad then as me if i am mad at her and i say no but she needs to listen...hope this works
