Gavin uses the word big (pronounced "dig") to refer to anything large, tall, high, in large quantity, etc. Usually if I ask him if he wants a cookie or a snack he'll respond "dig!," meaning he would like a large cookie or a lot of cookies. He has an interesting word for small - baby, pronounced in plural form "dadies." Anything small gets refered to as a baby. Yesterday we had sweet potato french fries with lunch. He picked up an unusually lttle fry, said "dadies" kissed it and then rocked it in his arms, well, like a baby.
