Sam's always seemed happy just rolling or crawling around on the floor (well, slithering on his belly) and even though he loves standing if he's lifted up he's made no effort to actually get there himself - until this morning when he just went over to the sofa, put his hands on it and stood up!
He looked as if he's been doing it for months! No wobbling or anything
...I reckon he's been secretly dancing around in his cot after I put him to bed. Would explain some of the strange positions I find him in in the mornings anyway
