One of the more memorable Super Bowl commercials was from Cheerios, where this adorable little girl finds out she's going to be a big sister...and barters with her dad that a puppy should also join the family.

My boyfriend's sister is expecting her second child also, and when she told her daughter she was going to be a big sister, the precious 4 year old said, "Can't we just get a puppy????"

While puppies seem to be a kid's barter system for getting what they want, there's also usually some kind of kid-humor when it comes to finding out if the baby is a boy or girl. Check out this little one's reaction when she finds out she's going to have a brother...
