Denial is a river in Egypt

She can see where she is going; she can see where she is going; she can see where she is going. Why does she fall down steps?

As Charlotte's mobility increases, I get more and more worried that we are going to find out the truth that she can see very little indeed. We have been having a wonderful time with her, she is funny and cheeky, she loves looking at books, she plays with all her toys in ways that seem extremely normal to me, she has been making great progress with both gross and fine motor skills, she is starting to talk a little bit. Aside from her sunglasses or squinting, I really don't notice much that's different about her.

But she doesn't look across a room, ever; and she has a tendancy to fall down steps. Before you get all concerned, she doesn't take a tumble down a flight of stairs, she seems to see them ok. It is a single step that appears to come out of nowhere for her and end up with her face down on the floor. Even in our own house, which she knows best of all, (where there is only one step in the entire property) she has crawled off it.

I don't really know where this falls under normal toddler behaviour and where this is happening because she is a blind child. In my parents house, there is a particular step that my Mum had to put a black piece of tape across because fully-sighted people kept falling off it.

Will a few of these tumbles make her more careful or will she end up needing a cane to walk around people's houses?
