A Full Belly

I have two nieces, one is 3 years old, the other 9 months. My sister's family lives with us, so I've had plenty of baby experience, and it's so fun to watch them grow! Apparently, they've been watching me grow as well... Last night, the 3 year old asked me why my belly is so full. Haha! She had been looking at it and touching it throughout the evening, so I was just waiting for her to say something. I just kind of looked at her, and she asked "Is your belly full?" to which I simply replied, "Yup!" Haha, I'll leave the real explanation up to her mother. She and my mom were joking about how they'll just say that Santa brought the baby, since my due date is around Christmas ;)
