I really don't remember how I did it, but y mom said I began reading newspapers.
First, when my mom was reading a newspaper and I was on her legs, I always pointed something colorful with my finger (frequently a logo or big colored numbers like discount announcements) and said "What do it says?". My mom always respond me, for example "It says, 'Coca-Cola' ", I made a lot of questions and sometimes my mom was tired of paying me attention.
I memorized a lot of logos and announcements like "50%". Time passed and then, if I saw a Wal-mart logo, Coca-Cola bottles with the number 30 and the sign "%", I told my mom "Wal-mart has 30% off on Coca-Cola". My mom was surprised.
Time passed, and when my mom didn't expected I began to read headlines without her help. I read things like "Fisherman found a dead man near to Panuco river".
