"CONGRATULATIONS!" on your new little man! He is just adorable!
We had a similar experience last week with a filly born outside in freezing temperature. She was foaled at 306 days by an experienced mare who has had 5 previous foals all born around 326-327 days. I felt terrible because I didn't even have her in the barn. Goes to show a person NEVER knows how unpredictable these precious little mares can be.
When I found the filly, her little ears were all frosted and she was ice cold and standing there shivering. I was so afraid that I would lose her. I did the same as you and dried/warmed her up with a hair dryer, blankets, heater and milked the mare and syringed around 18cc of colostrum into her.
She is now 10 days old and definitely has a little attitude-I really think that strong desire to live and that little attitude is what has helped her to survive.
Love your name choice Causin' a Commotion!!
