On this picture it looks like we can just put him on his playing area, and then he stays there and ... plays.
Mwuahahahahahahhahahahahah! This is not the case. He has found out how to move around. I guess crawling is not the word, it is more some kind of pushing himself around. He can do this both when he is lying on his tummy, using his arms, and moving backwards. And on his back, using his feet. Also, he finally decided to turn around from tummy to back position for the first time... when he had moved about 1 m away from his soft play area on to the hard wooden floor. So he hit his head, ouch.
Also, it has rained a gazillion hours.
