Will woke us up really late on Sunday night crying. For one of the few times since he has been born, he awakened Patrick, and I did not hear a thing. Patrick came back and told me that Will had had a nightmare about Jack. A few seconds past and Will started crying again. So Patrick went back in to check on him. This time Will insisted that they go into Jack's room to make sure "Jacks otay." So Patrick took him in, and Will made sure Jack was in his bed asleep. Once he was assured, he went right back to sleep and didn't wake up until his usual time.
I'm so happy, that at least for now, Will wants to look out for Jack and make sure he is "otay."
