I highly recommend Dr. Sears Discipline book. 3 year olds I think in general are just frustrating :) I have a 5 1/2 year old, a 4 year old and 2 year old. My 4 year old boy right now is trying to say the least! They are struggling to be independent and yet want to still be attached. They are learning SO much, and don't have control of their emotions yet. It's completely normal to have tantrums and cry and scream, and it's good for them to know that they CAN let it out. At the same time, modeling appropriate responses for them helps - showing them how to beat the couch to release their frustration instead of hitting you, or yelling into a pillow, or having a room that's their "scream room" can help. Distraction can work, or just acting crazy silly to diffuse a situation. They need to know it's OKAY to get mad or upset, but that there are ways to vent that frustration. And being firm and consistent is key. If they know that mom will ALWAYS say no to whatever it is, then eventually they will get it and not do that any more. It takes a LOT of repetition, but eventually it will sink in :)
