I cannot get enough of how sweet and adorable an 18 month old can be. Kylie was just that. So sweet in her own right, and absolutely adorable with her little sister Mackenzie. Having two little girls myself with a similar age gap, I know first hand how difficult it can be at times. I have also experienced the pure joys of having two little girls, and the joy far outweighs the tough stuff. Buckle in, and enjoy the ride!
