Wow i've been through a few 3 year old tantrums and never one that lasted that long, must of been a doozy!

Um, I don't know - if I know what sets them off, I try to avoid it, or try to get to a resolution as quick as possible - and distract, distract, distract! At that age it still works.

DD1 is 4 and she didn't want to go to bed tonight so she started chucking one in the kitchen and I quickly skipped away and told her we were skipping to her room - will she join me? Skip skip skip - she's still standing there whinging. Skip skip skip - she's stopped and is looking at me like I'm a complete tool.

Next 5 seconds - tantrum avoided and she skipped with me to the bedroom pmsl!!!

Anyhoo - thats the only tips I have. Cut them off before they get going, distraction, or being a complete tool.
