Thanks to everyone for the support and kind words (and to one someone in particular for the cookies). It means the world.
Sidamo is doing great. We've been spending a lot of time indoors to prevent further head injury, and that has led to a rediscovery of train tracks. We've also done some more painting (really, why do I bother giving Nora paper?), reading, and a bit of driving each other crazy, just for good measure.
The weather is absolutely gorgeous, and he'd much rather be outside tackling his friends and doing other unsafe things than staying cooped up in the house. Which, I presume, is what led him and his friend to SNEAK OUT OF THE BACKYARD and go to the neighbor's house to ride scooters yesterday. He got seriously mad at me when I had to physically remove him from the scooter and, of course, lecture him about not leaving the house or yard without notifying an adult. I (and the whole neighborhood) heard an awful lot about what a "not nice mommy" I am, which, to be honest, made it a little difficult to stick to my "be a nice mommy" resolution from the other day.
Here's hoping that the weather holds through Thursday, which is when he's allowed to get back to his normal activities. And here's hoping our patience with each other holds through then as well.
Thanks again for all the love!
