We had a big family get together over the weekend and my cousin brought her twin toddlers. Fun! Most of the extended family, myself included, sees the twins about twice a year. They are fraternal but we can't tell them apart. We were using the 'Susie has pigtails and Sara has a ponytail' method. That works if Mom introduces them first but now they are of the age where they can venture off on their own. I heard "which one are you?" dozens of times. "Hi, what's your name?" sounds distant for family members and, like most toddlers, they aren't very forthcoming with their names.
How would you like people to find out your kids' names?
