However, DD is now 4 and is a complete joy and very easy going. Some of the "easy" babies I knew became much harder to parent as they aged.
It's a personality thing. Just accept this and try not to compare your child to other kids (it's really hard, I know).
My son was like this. I think he was frustrated because he couldn't do what he wanted as soon as he wanted - he wanted to be understood, wanted to be mobile, wanted to DO things, and until he was old enough and his body/mind were able to do them he was just so frustrated. It was really hard.
