Twins

I went to Costco on Thursday with Lana and Georgia. They sat side by side in the shopping cart, as they always do. In the past few months, since Georgia has been looking more like a toddler and less like a baby, people have been asking me if they're twins. Usually it's when we're out shopping somewhere and they're sitting down. The other day at Costco I had four different people at four different times ask me that question. FOUR! I wasn't even there that long. I don't think they look like twins, but then again, I know them and know I was pregnant at two different times, so I could be biased. What do the rest of you think?
