Counting numbers

Lani was playing with Ethan this morning, carried him and sat him on her stomach. She then said, "Ethan, let's count" and started counting "One, Two, Three, ..." Ethan's face lit up, he smiled, and suddenly started counting with her 'Huhhh, huhhh, Teeehhh, Huhhh, Hahhh, Heeehh, Huhhhhh, Huhhhh, ..."

It was really fun to watch. He's like really counting but with Huuuhs and Haaahs.
Unfortunately, I didn't catch it on video. Sayang!
