It already feels like things are going by fast with Alex. When he is awake, he is more alert. He opens his blue/gray eyes wider now. He likes to move around, especially his arms and legs. If he really tries, he can roll onto his side. He is far from rolling over, but this is a start.
Here is a picture from when he is 2 days old. At over 3 weeks old, he already looks older and has filled out some. We don't swaddle him much anymore because his wiggles his way out of the blanket.
