First, be glad that this is a biography, not an autobiography (so, you may choose the POV).
I'd be inclined to find a "cute" POV, like:
I was just a typical baby pacifier hanging on the shelves of Toys"R"Us until Abbi's mom bought me and introduced me to Abbi. Abbi was just two days old by June 10th -- which meant she was born on June 8th. It happened at the big local hospital in Meadowbrook, Illinois. The most interesting thing about Abbi being born was that she choose 3:45 A.M. as the arrival time.
So, at a mere two days of age, I replaced a real nipple and a baby bottle in Abbi's mouth -- and she bit me. Boy, was I glad that this kid didn't yet have teeth. That would happen 4 months and 3 pacifiers later; I would be long lost by then.
Make it fun to write and it will be fun to listen to.
First, make a checklist of the facts to present. Then, choose several facts and add a "cute" observation from the POV of the story teller. Humor is systematic! So is drama! Interest comes from being able to "relate" to the story, so you should know who is in the class and some information about what they like/dislike. I say this when coaching students for science fairs: "Observe everything you can about the judges and then talk to their interests, not to your interests."
