4 months old

Yoshi is 4 months old today. Recently, he starts to interact more with his toys, learning all the different tricks on how to play with those, sometimes just by observing how we show him. Can't believe how fast he learns.... Yesterday, I was shocked to find out he is able to turn on and off the music box next to his crib. If u think it's just a co-incident, your are WRONG!!! At first he was using his feet, then later on with his hand. He turned around his body, trying hard to press that button.....oh no.. very soon, he can climb out from that crib then......
