My grandson is five. He's outgrown his Dublo blocks and is asking for Lego for Christmas. In the stores I find shelves of Lego sets, but on the opposite side of the aisle are shelves of Mega blocks that look similar, in equally attractive sets.
I understand that they are not interchangeable.
I think my grandson is the type of boy that will want to add to his collection over the years, so it seems important that he start with the right set.
Any experience out there?
