Ultraman, Ryan is also doing Yoiur Baby Can Read. I started him when he was very very young, that time he couldn't last very long. On the starter DVD, sometimes he could last until twinkle twinkle little star, sometimes until eentsy weentsy spider, never finish. So I stopped the DVD for a while and used only the books instead. Then start the DVD again a while later, and he could really sit through the whole DVD and I could see that he was really paying rapt attention, won't move for the whole DVD (I was so tempted to leave him in front of the TV and do my own stuff, but didn't). Now when he watches the DVD (the one that he has watched before), there are some reactions - sometimes he will smile, sometimes he will make a sound, sometimes he will move his arms/legs.
