you brave, brave, wonderful mama!!!! I'm so glad it went well.
wanted to add, for a couple of months down the road...I'm not sure how it will be for your son, because the incision site seems to be fairly contained (my son James fist and hand sized pieces of his skull taken off, and the scars were very long), but don't be alarmed if a few months down the road your son gets one or a couple of very hard bony bumps near the surgery site. They won't show through hair, but they'll be very obvious to the touch. If he gets them, they're nothing at all to worry about. It's just the skull healing, and it tends to heal kinda bumpy in spots.
But like I said...that's for down the road. And how GREAT that now there's a road to look down WITH THE SURGERY BEHIND YOU!!!!
keeping him in my thoughts. Hope his recovery is swift.
