2 more things i realise about max:

1) he can say from letter A-Z repeating after you.
2) he is very sharp boy. he knows when you are going out and he will follow you very closely so that he won't lose you. very sharp and smart boy.

just now bring him to the barber. although he is 2 years old, but he can sit alone on the chair. he can sit very still and he look very serious. way cool.
