No Special Twin Bond

My two week old fraternal twins doesn't seem to have a special twin bond/connection. They sleep better separately. They dont find comfort in touching...actually seem annoyed if they touch. My husband was convinced before they were born that the twin bond was a made up perception for fraternal twins. They didnt share anything in the womb except space in me. And that any bond is developed over time because they are raised together. No different than a bond with an older or younger sibling really. I didnt believe him, but now I am beginning to think he was right. Do anyones fraternal twins have a bond at birth, or do we just see a bond becuase we want to see one?
