Jacob's progress

Last week in Krakow my baby who used to lay on the back or front without moving much started sitting without any support and kneel holding in to the side of the bed. It's pretty scary for me, because I would never want him to hurt himself. I asked my husband to lower Jacob's bed at home. We came back home yesterday and I was really happy to find out that the bed have been already lowered. We have been away just for two weeks and he progressed so much. I noticed that he is looking at his old toys differently noticing little details (e.g. spinning wheels).
