I can understand your mother’s view. My son is my world and my world is crushed when harm comes to him.
Since writing this story I’ve become more involved in his skating and we’ve even built a mini half pipe skateboard ramp in our backyard. This has greatly reduced my anxiety. It’s helped me realize that he will continue to fall and get cuts and bruises (it’s the nature of the beast) but the extent of his accident is a rare occurrence.
