My kids both talked really early too. My son would sometimes startle people when they heard these grown-up sounding words coming out of this tiny little infants' mouth.
I remember once going to the grocery store with my daughter when she was still just a toddler in the baby seat of the cart. I had just picked her up from daycare and we were picking up things to grill hamburgers on the patio when we got home. I was done and heading for the checkout when she said, "Don't forget the chuckle, Mommy". What? "Chuckle, Mommy! Chuckle!" She was so insistant and I knew that SHE knew exactly what she was talking about. So I wheeled her up and down the aisles and told her to look for the "chuckle". We got to the picnic supplies and she got all excited, yelling "Chuckle, Mommy!" She was pointing to a big shelf of CHARCOAL ... I had completely forgotten to get it, but she didn't forget!
Another time at about 18 months old she was in the pediatrics ward of the hospital with viral pneumonia but she didn't seem to feel all that bad. She was supposed to stay in her room, which was hard to do because the whole hallway was full of toys, bikes, wagons, lots of other kids, and a big play room. She started to cry and kept saying she wanted to "see the pipple". I thought she meant "people", the other kids, that she was lonely and wanted someone to play with. She begged and pleaded, and somewhere along the line, "pipple" turned into "bice-pipple". And I finally figured out that she could care less about the other kids, what she wanted was a "bicycle", one of the Big Wheel tricycles that the other kids were riding up and down the hall! Mama was dense, but she finally got it!
