Wow, What a Night....

Well last night was my most challenging night to date (while be a parent of two). We were out all day,which was great, Wyatt slept all day and Ethan was very well behaved all day. At about 5:30, in the middle of Ethan and I's dinner Wyatt started crying, the crying didn't stop, literally, until 1 this morning. And it wasn't just any cry, it was a scream! Ethan went to bed at 7, and I was just hoping to heck that Wyatt's cry woudln't wake up Ethan. Thankfully it didn't.
I don't know how to explain it, Wyatt was screaming, screaming screaming ALL night, He would stop to eat, but not like he usually eats, he was suck for a couple minutes then stop, look around and start crying, he couldn't figure out how to latch like he usually does but he was getting lots to eat I mean he ate all night (that was the only time he was quiet). It just wasn't his normal eating habits. He was exhausted, I could tell he was TRYING to keep his eyes open and he was yawning every couple of minutes.
I did a little bit of research online (typing with only one hand, because heaven forbid I put him down). I got lots of suggestions from friends as to what his issue could be and things I could try to get him to stop crying. Trust me I tried most of them.
My good friends at google suggest Colic. So I looked up Colic, Wyatt seems to fit into the Colic category, but then a growth sprut was also suggested and that makes sense too. He was hungry all night, and would eat every time I tried, but he wasn't frantic for food which makes me think that it possibly is more likely colic than a growth sprut.
Colic, on the internet, is described as a baby who crys for more than three hours in a row, three days in a row. CHECK... Wyatt has accomplished that. I finally got him to sleep around one, we were on the couch, my head was in a very uncomforatble position but I dare not move incase I woke him up.
He actaully slept (when he fell asleep) for his longest ever, we woke up at 5:20. So that is four hours and twenty minutes, I slept through three phone calls (dumb faxes), i woke up with a terribly sore neck, but happy that we had actaully got SOME sleep. We had a feed (which seemed to be back to normal) and were back to bed until 8:30.
I had a minor breakdown this morning when Ethan woke up and Wyatt was screaming. I just feel so bad that I can't give Ethan the attention I want to. But i'm feeling much better now as Wyatt is asleep!! WAHOOOOOooooo.
I am a little nervous about tonight though.... perhaps it was just a one time deal??? Maybe? Hopefully?

I appeciate all the helpful hints from everyone, I'm going to see if cutting dairy and caffiene out (suggest by a friend and many many websites) will do anything to help. I will try it for a couple weeks, if nothing changes then I will go back to my tea and chocoalte habits :)
