Havings twins is a funny thing. There are so many things that they do the same, and some things that they do differently, but it can be such a stark contrast having them do it at the same time.
Well, when you have boy/girl tiwns, there is even more of a contrast, and the inevitable has finally happened.
Emma is now significantly taller than Joe. Oh no!
This has caused Joe a little anxiety so Troy just keeps telling him that he will eventually catch up. (We hope.)
