I saw some ‘mega blocks’ advent calendars in the shops through the week. As the days go by the children would open a little door, take the blocks out, and build then another piece of the set. We don’t collect mega blocks (and I didn’t realise there was a Lego version) So I made the boys one instead. It’s pretty nifty I think, they boys think it is fantastic! They remind me every morning, and spend time together following the instructions and building the set. The brilliant thing is, it’s totally reusable for next year.
