Digesting Information!
If you have already heard this term "alphabet dosas" before, it means you are a creative (South Indian) parent of a 3-5 year old. I heard this term for the first time yesterday and was curious to know about it. The mom was more than excited to explain that she makes the dosas in different shapes resembling alphabets so that the kid learns the alphabets and also has fun while eating different shapes.

(Is this what they mean when they say digesting information???)

I don't have to try hard, all my dosas are alphabet dosas. May be you will have trouble figuring out the alphabet:)
