My son is 4 and at times horrible! My oldest daughter is now 9 and went through the same thing at 4. I prefer 2's over 4's any day. At 4 the back talking, attitude and argueing everything begins, makes me nuts! you're not alone, but just so you know, it didn't really get much better past 4, just kinda changed. I think it's that the kids want to be more independent, yet are so very dependent. Just bare with it. I did make a behavior chart for my 4 yr old. It's for 30 days, every day he is good he gets a star, if bad day, no star. When he gets 15 stars, dollar store, 30 stars is Chuck E Cheese. This seems to help a little and hates not getting a star. Took us about a month to reach dollar store. Good Luck!
