Hi Taff!
I take it your child is 10-months old? Disney offers a number of things to do, even for our smallest and most precious...
Here are a few things I can say my son enjoyed when he was a toddler...
Downtown Disney
Downtown Disney has a very small carnival-type section, which includes a carousel and mini-train that goes around a track. My son wanted to get on and do this multiple times.
Magic Kingdom
What Magic Kingdom visit isn't complete without enjoying rides such as It's A Small World, Peter Pan's Flight, Dumbo the Flying Elephant, etc. All of these are toddler friendly, and move slow enough without the risk of falling out.
Epcot
My toddler son really loved Innoventions. At the World Showcase, you'll find stations called Kidcot Fun Stops, where children can try to draw, mess with a craft, etc. Sometimes at that age a crayon and paper does wonders, a little Picasso! :-)
Hollywood Studios
Playhouse Disney-Live on Stage (show) and Playhouse Disney at Hollywood and Vine (singing and dancing while eating), offers Playhouse Disney characters and both are fun.
Animal Kingdom
Affection Section lets children pet the animals. Discovery Trail lets them watch some of the larger animals. The Boneyard has slides and a sand excavation pit that will keep toddlers entertained for hours.
You'll also find shows such as Monsters Inc. Laugh Floor (MK) and the Epcot Character Spot, where your kid can meet some of the most famous of Disney characters.
Also, keep abreast of the itinerary at the resorts. Many offer toddler-friendly events at no extra cost.
