All children hit age 2 and want to be independent and do everything themselves, but they are fighting all the boundaries that we put in place to keep them safe - hence the temper tantrums. Twins are no different, except...
Well, twins learn early on they have to share (or fight it out), they learn they are not individually the center of attention from birth and so acknowledge that the world around them only sometimes revolves around them. I was lucky enough to stay at home with the twins for 3 1/2 years (before I craved adult conversation so bad I went back to work). They were my world, but they knew they weren't the world.
Five years after they were born, Bradley entered our world. He was (is) the center of the universe. Just ask him.
The twins have doted on him, due to the economy he stays at home with Daddy all day, and is the center of Daddy's world. I come in juggling and try to spend individual time with all of them, but little man expects time of his own. All of these things together have made him very outspoken about "his world." If he is busy and anyone tries to talk around him, he gets angry at the distraction from his world and
This happens in the car, while he's watching his movie, and even at the dinner table when we are trying to learn about the twins day at school.
We are working to teach him that the world doesn't actually revolve around him, but have you tried to explain that to a 2 yr old? So here is my theory - just teach him a new word. I am working on "don't" then he can yell DON'T! STOP! DON'T STOP! and we'll all be able to carry on with our conversation.
If you want to learn to argue with a brick wall, practice on a 2 year first. ~ me
