My husband put our preschooler to bed the other night after I fell asleep.
I woke up to find this on the living room floor in the morning.
This is our most recent father/son block creation. A dump truck. Complete with a cab, wheels, and a skip.
To me it was fun to see what they created.
To our preschooler, it was valuable time spent with his dad and a chance to build without his little brother knocking it down every few seconds.
