For the time of yoear you will be visiting, you probably won't need to follow any touring plans. The only advice I'd give you is to get to the parks as close to opening as possible.
MK- You'll probably be spending quite a lot of time here, since you have a young child. Get there at park opening, and hit Fantasyland right away- do Dumbo, Peter Pan, and Pooh early. They are the three rides that really get backed up. If you start early, you can do all of Fantasyland in about 2 hours (you'll even get to do some things more than once). Biggest tip- do Dumbo first. If it isn't crowded yet when you get off, go on and ride it again.
Epcot- Do Test Track first thing, and then Soarin' as soon as you get there in the AM (or get a FP and ride Imagination and Living Seas, then go back to ride Soarin'- your FP time should be up). Save World Showcase for later in the afternoon or evening.
MGM- ToT and RnR get crowded by midday- do them early. Voyage of the Little Mermaid also gets crowded later in the day.
AK- Ride the Kilimanjaro Safari as close to opening as humanly possible. The animals are much more active early in the day. If you do Kali River Rapids, go right before you leave for the day- you'll get absolutely SOAKED, and you might get cold in January.
Have a great time, and get to the parks early!!!
