I am 1.5 month old

How fast did you grow last month? Well, I grew 5 cm. Isn't that amazing? I also get stronger every day. Yesterday, I was laying on my belly and I could hold my head up for 3.29 seconds. A new world record!! I must have impressed mom and dad because they were very excited about this performance.
Now and than, we go out all together. We go to the mall, the supermarket or eat a pizza at the restaurant (not me, i am still on a milk only diet). Everywhere people stop and try to to look at me. Even some try to pinch me but mom made it clear that that's not done. There must be something very strange about me that all people react like that.
