Tomas' first words

Toria has been trying to figure out how to write words. She is constantly asking "how do you spell..." "What does an 'H' look like....". Usually, Tomas (who does sound out words) ignores her.

Not yesterday.

Toria: Tomas, how do you spell pee pee?
Tomas: (sounding out letters) puuu puuu puuu P and another P, Toria!
Toria: Thank you Tomas
Tomas: Hey mom - I spelled my first word P P makes Pee pee, right?
Me: Yes, Tomas, err, way to go!

And that is how my son's first 4 speaking words were:
1. Dad
2. Guck (for Truck)
3. Bulldoder (Bulldozer)
4. Mom

And his first writing word (besides his name) is: P P
