Alex doesn't take naps everyday anymore, but I make him stay in the now-playroom for an hour or two while Mary takes a nap. Some days he comes out looking pretty tired though, and one afternoon he actually fell asleep on the couch. I had to take a pic, because my kids usually don't fall asleep anywhere except their beds.
These guys are best buds. One morning they were cuddling on the couch while watching a show. They kept changing positions, but Mary kept her arms around Alex the whole time. So sweet!
Alex loves to teach Mary things and correct her mistakes. Sometimes it's Mary doing the correcting though. As I have mentioned before, Alex is fascinated by space, and a few of his books are older and still include Pluto in the list of planets. I tell him not to include Pluto, but sometimes when he is rattling off the list he forgets and Mary is quick say, "No, Alex. Pluto is a dwarf planet." It's too funny :)
