Sara, i have done a fair bit of standing next to xx (be it digger, cranes, even the truck from the water company to do a scope through the sewage) for a significant period of time to let DS watch. Usually the guys are very friendly and wave to us. DS is still very into it!

Reading, doing puzzles, rolling cars when he is almost flat on the floor watching how the wheels turn, DS also loves launching onto the bean bag! It is still in a box after we moved as we dont have space to put it out anymore...
DS also likes to set out our picnic set and the colours have to match, cup, plate, bowl, and cutlery.
