Seriously... he's adding words so fast, I can't keep track any more, and we're rapidly approaching the point where we just want to ask him to STOP talking for a minute! LOL
He's been on an animal kick lately, identifying animals in his books:
Monkey
Elephant
Bird
Doggy
Pitto (Hippo)
Rawr (Lion)
And he's adding more animal sounds to his repitoire:
Ooo Ooo Eee for a monkey
Rawr for a lion
Meeoooow for a kitty
Moo for a cow
