Goldfish - i use my hand and bit his palm. At first he cried, but after sometime, he think its a game, when i bit him he pouts then do the same again. So when i put on a stern face, he will cry.
the best part was the other night, after i bit his hand, he crawled away, then he sat there, hit his own head and say "pain", then hit his own hand , imitating me. So funny.
yes, little e can say simple words already. i do think they only understand temporarily.Afterall , like my dad says, they can hardly understand. i think they are in their absorption phase so monkey see monkey do.
