It is not easy to describe the personality of someone, particularly if you know him only for a little more than 2 weeks. On the other hand I can say I know Ivan for his entire life now, so I can share some observations. Not sure whether it is him or us mostly, but it feels much more relaxed with him. Apparently the second child syndrome works perfectly well with us: we are much less concerned, much less careful, and much less stressed out than we used to be with Maia. Maia, I have to point out, was never a difficult child. But we were so unaware what to do and how, that we probably made her cry much more. By not giving her a pacifier, to begin with. Ivan gets one immediately after milk is over, and seems to like chewing it while staring at interesting objects with his slightly unfocused eyes.
But I am certain that there is a great deal of himself being calm and quiet. One thing that is really important for him is to know that there is someone around. But if he feels a touch, hears a voice, or sees a moving silhouette, he immediately relaxes and gets obviously happy. That is of course if he is not hungry. Emese's constant presence is probably the greatest thing for him these days. In some of the first evenings I used to take him over with me in the living room and put him to sleep on my lap or on the sofa. But he learned to sleep overnight so quick that there is no need to do this anymore. He simply sleeps in his bed now, and lets Emese know when time has come for food.
