It sounds like he is doing great! Really! Ya'll are doing a LOT at home and the Y and he is getting regular non painful input to help reset those nerves. The daily manual massage surely goes a long way towards this. Go Mom! It DOES feel slow during these stages but a slow pace is okay. He is moving forward and will get better and better, that's all that matters. Focus on the long term goal. If continuing to use the walker at home gives him more "up" time without the boot since he can only go twenty feet or so then go for it. No reason not to use it at times if that supports more movement that isn't painful.

I am just so glad to hear your son is doing better. Keep us updated. I know there was a collective sigh of relief when you posted that he was making improvements.
