Nolan is one expressive baby! I'm not sure why, but it seems like he communicates a lot more clearly than Nico did at this age. Even as a newborn, Nolan's cues were relatively easy to read. Of course, it may be that Vic and I are more experienced parents now, but it really does seem that Nolan is easier to understand than Nico was.
These are not the most flattering photos of Nolan (he really doesn't look like such a pumpkinhead in real life), but it gives you an idea of the faces he makes.
