More of the LEGO train

Tonight S2 put LJ to bed, so he could spend some time with him and so I could spend some time with CJ and the LEGO train.

He has been building a little each night, and tonight we were finishing a truck (which will carry a bulldozer). It is amazing to watch - he concentrates so hard on it, following every instruction and carefully putting it together.

And once we are finished, we have to put it on the track and have the train pull it around for a couple of laps.

I love these little moments with him... But it reminds me that he's growing up so fast.
