I know how you feel, DS was in his brace for his first birthday and Christmas, I was devastated. I also struggled watching similar age children reach milestones before DS. However he is a total legend, he is one of the most gentle, thoughtful and kind kids and has a wicked sense of humour, I feel like he is wise beyond his years, so I agree with PRM, they just focus on other developmental areas while instead of the mobility ones.

I've almost forgotten about our brace time now (6 long months) and every now and then I see a photo or the actual brace (its in the top of his wardrobe, for some reason I kept it, dunno why, it was a big part of his first year etc etc) and I am amazed, it was so hard at the time, but now it seems sooooooooo long ago. There is definitely light at at the end of the tunnel
