I don't know why this has been such an issue for me. My son loves garbage trucks, loves watching them, loves playing with them, loves reading about them. He has a small collection of model garbage trucks (and bins) that he treasures.
But for some odd reason I insisted that they be packed and hidden away in cupboards, draws and boxes. They are his favourite and most played with toys - why not honour him and his possessions by leaving them out, more accessible, on his shelves.
So today I took the puzzles and trays off the shelves and out came some garbage trucks. They have some educational benefit and are a whole heap of fun - for one little boy anyway.
