Learning to Copy - Basic Sign Language

When Richie was approaching 1 year old, he's starting to copy our behavior. It made easier for mommy to teach him Sign Language.
It happened during our lebaran holiday. It's just 10 days but he improved a lot, mommy guessed his brain was learning faster and faster now.

Some Sign Languages that he could do now :
1. Waving Bye bye
2. Kiss bye
3. Hi-5
4. Shake hand
5. Hellow daddy (put the handphone / right hand close to the ear )
6. Haiii ( hand's up)
7. comb the hair (put the comb to his hair)
8. feed mommy (put his spoon to mommy's mouth)
9. nose (point his nose)
10. dancing (he moves his palms like dancing)
