The talking baby?

Sammy is only eight weeks old and he's already saying his first word. 

Probably.

We always greet him 'Hello Sammy! Helloooo' , and being the sociable baby, he smiles the cutest gummy smile possible and tries to reply back 'whooo' or 'whaaaugg'.

Recently his reply' becoming more and more clearer.  He's saying "hewoo".
