I totally know what you are going through! My son was 2 in March and just before that his behaviour was unbelievable. He would scream and scream if he got frustrated and sometimes got aggressive with me. You have probably heard it all before but the best thing i could do was to distract him ie: really ethusiastically say "look, look at that plane/butterfly oh wheres it gone" and keep the discussion going untill she is searching for it. The best thing i ever heard about a childs behaviour is "If you don't like it, Ignore it" it sounds so simple but it's true.
