Trucks or cars (that are ok to get wet)
Theo has taken his trucks in both the bath and shower. He really became active with them while he had them in there with him during a bubble bath.
He would give them “baths.” He would take bubbles and cover the trucks and once it was covered he would hold it under the running water to wash it all off.
Just allowing him to take the truck in and adding bubbles, gave the idea to Theo to do this (I didn't say anything while this was going on so that I would not affect his exploration and actions).
There was no initiating, just occasional describing what I saw him doing in a very subjective way such as “You're putting bubbles all over your truck,” as he covered them with bubbles.
He took time to do this sequence of covering and rinsing the whole bath time.
