C.,
Good for you not letting him cry! He is 8 weeks, not 8 years old! He is not spoiled and you are a loving, caring Mama. So many people told me I was spoiling my baby, and now they see him, they think he is so happy! I went (and go) to my son when he cries!
I haven't read very far, but have you checked out whether he's teething at all, too? Drooling is a good sign, and fingers in the mouth. Interesting note: I wash my hands, but let them air dry before putting them in his mouth. He rejected the water that was on them once. First time I tried this, he clamped down a few times, then was smiling. I didn't think they'd start teething (the teeth moving around, not just popping out) at 3 months! This would explain the waking out of the blue.
I didn't see anything about formula vs breastfeeding? Formula I have no experience with. BF can be interesting! Just don't forget to eat. Garlic is in just about EVERYTHING, I've found.
Movement - if you didn't stop moving when you were pregnant, except for sleep, then your DS (dear son) is going to associate movement more than ever with being safe. If you don't have a swing, you may wish to purchase or find one (and with different directions for swing, too - for a while my DS wouldn't tolerate cradle swing, only side-to-side).
Movement - sling will help a bit too. Does he like to face out all the time? Or cradle all the time?
You think he's having a growth spurt - Has he been eating more?
There are some massage techniques for colic too - just learned the I Love You technique, though I don't think I could describe it adequately. There are massage classes here in Rochester, too.
I know this can't have been much help, I just wanted most to say good for you, holding your baby, and not letting him cry. This is so important for him learning that he can trust you.
