Wonder Week 19:
The World of Events
The realization that our experience is split up into familiar events is something that we as adults take for granted. For example, if we see someone drop a rubber ball, we know that it will bounce back up and will probably continue to bounce several times. If someone jumps up into the air, we know that she is bound to come down. We recognize the initial movements of a golf swing and a tennis serve, and we know what follows. But to your baby, everything is new, and nothing is predictable.
After the last leap forward, your baby was able to perceive smooth transitions in sound, movement, light, taste, smell, and texture. But all of these transitions had to be simple. As soon as they became more complicated, he was no longer able to follow them.
With mental leap 4, at around 19 weeks (or between 18 and 20 weeks), his ability to understand the world around him becomes far more developed and a little more like our own. He will begin to experiment with events.
