Growing up, my father was blind and ended up being a stay-at-home dad while my mother worked. As young kids, my sister and I knew that he had limitations and didn't do things the way my mother or other kids' fathers did them. However, he created systems for getting things done in his own way. As a result, simple things like cooking meals for us and making sure we were clean and dressed may have taken a little longer than if he could see, however, it got done. The one thing my mother did that he always appreciated was to never jump in while he was attempting something (as long as nothing got dangerous, of course) and never comment on how long it took for something to get done. We all acted as if his way was the normal way...And eventually, it did become the normal way.
Your husband may have to create some different ways of doing things, for example, maybe having diapering stations setup so that its easier for him to navigate. But, at the end of the day, his desire to help and his love for his daughter will come through larger than anything.
My dad has since passed away a few years ago, but I have such fond memories of everything he did for us as children. I also appreciate the challenges in day-to-day operations that he faced on our behalf. Its given me a perspective on challenge and disability that I know I'd never have if he'd been sighted.
