PLANES and LEGOS!!!
Wooden railway tracks have been a hit for years. Both Isaiah and Owen have played with them on and off since we got them a few years ago. One of Isaiah's favorite things to do is let a battery operated train start at one end of an uncompleted track and see if he can continue building the track before it catches him on the other end of the track.
This particular day he had a huge zoo along the railway. He decided the animals needed much more space and set off to build them a house with legos!
Great fun for both kids... and me!
