My first kid ... so easy to get him to laugh as a baby.

Second kid... nope he's such a serious baby. He does laugh but it takes a lot of extra effort. Most of the time he gives us a pity laugh!

I was talking about this to a friend of mine and she says she thinks my second kid is an extrovert because he needs more simulation to get excited.

I thought that was an interesting theory. I'm going to take a poll!

I know most people don't know if their kids are introverts or extroverts yet but maybe take a guess?
