Monkey loves building towers, with blocks, duplo, bean bags, anything.
At the moment he loves making a tin can tower in the kitchen. I try and persuade him to build them on the floor, which he does to start with, but he invariably starts lifting the tins onto the worktop 1 by 1, then climbing his stepstool and building it on the worktop. It tends to make me a bit terrified that he is going to knock them over onto himself and get hurt, but so far so good (fingers crossed, touch wood).
Anyway he built this tower yesterday and as you can see, he was dead proud of himself
