Who's Who??

We have a bit of confusion in our house about who is who. Now they know who Mommy, Daddy, Elmo and Dora are no problem. The confusion only is when it comes to who is Luke and who is Carter. For the longest they were both Luke to both of them. If Carter looked in the mirror he would say Luke and if you pointed to his brother he would also say Luke. The same with Luke. So we would go through all our names, point to each other and get them to say the correct names (still not really saying Carter to well). Then we'd ask who's that (pointing at Carter) and they both would say 'Luke'. Anyway, I think you get the picture here. Well I guess all our hard work paid off because now they are both Carter. Ugh!! Thank goodness they aren't identical, then we would all be confused. Well regardless if they know their own names at least they know Mommy, Daddy, Elmo and Dora.
