i'm too little

I was reading a counting book to my two-year-old niece. She can easily count to ten, but this time she stopped at one and said I can't, I'm too little. It broke my heart to hear her say that, especially since she has been fiercely independent and confident since birth. She said it again when time came to clean up her toys and I realized that she had learned that excuse for not doing the things that for whatever reason she didn't feel like doing. And I kept thinking about those three words. I'm too little. And I realized that I've been saying almost the same thing to myself. And on me, the excuse is much more pathetic and ridiculous than on a two-year-old.
