So Samuel did this today. I'm not bragging or anything (I'm bragging), but are 20-month-olds supposed to be able to carry out death-defying feats such as this? James was barely helping him, by the way. He's totally sussed out climbing on his own.
Talking of James, Samuel is completely obsessed with him at the moment. Daddy only has to leave a room and close the door behind him to elicit a volcanic paddy. This morning as James took a shower, Samuel spent ages just lying in front of the bathroom door trying to peek under the crack, sadly and repeatedly whimpering 'Daddy'. It was like a scene out of Greyfriars Bobby.
