Hi Erin!
Glad to see you're planning now because your trip will be here before you know it!
Isn't
Mickey & Donald Have a Farm the cutest? As of right now, there aren't any attractions specifically related to it but you never know what could change between now and January 2014. However, your 2-year old can see Mickey and the Mickey Mouse Clubhouse gang at
Disney Junior - Live on Stage at Disney's Hollywood Studios. When my boys were that age, they loved singing and dancing to their favorite Mickey's Mouse Clubhouse tunes there.
Your 2-year old can also experience some hands on animal fun at Rafiki's Planet Watch at Disney's Animal Kingdom.
Affection Section is a petting zoo area with goats, sheep, cows, llamas and more. Its also a great place to let little ones run around and burn off some energy. Be sure to take plenty of snacks and drinks with you as there isn't a lot offered at Rafiki's Planet Watch.
Also explore
Tri-Circle-D Ranch. Your little one could go for a pony ride, check out the beautiful horses or the whole family could go for a wagon ride.
Please feel free to visit us with all of your planning questions. We're hEAR to help!
Wishing you minnie magical memories :-) Allison
