One of the funniest interactions I had with my eldest daughter was the day we baked cookies together, when she not yet 2. She was verbalizing a lot, but also signing "milk" and "more" quite a bit. And when she bit into her very first chocolate chip cookie of her entire life, she immediately signed "more" and said as much through the mouthful of cookie.
At about the same age, I bought my son a mango lassi. He looked suspiciously at it, but took a sip. With a look of shocked delight he tilted it back, back, back, and emptied the cup!
Then he put it down, looked at me, and said, "Want more!"
I'm looking forward to kids out of the house. But there are some moments that I treasure.
