I kind of figured there's not anything you can do, but didn't know for sure. I mean, they don't put plates in their heads or anything, do they? I was wondering about some type of tiny helmet. Those little bike helmets they make for even kitties would probably be way too big.
All I can do is be careful and pray he's going to live a long, long time. We keep a really close eye on him. Weigh him several times a day. His weight can vary, but for the most part, he's going in the right direction. My daughter dropped off her 2 yorkies today while she goes out of town for the weekend and commented on how much he's grown. He weighs 1 lb. 4 oz......and he's 'grown'? lol Actually, from 3.4 oz. in 9 weeks, he has grown.
I hope God's plan for him is to live and live well.
