Within days of receiving Rosalie’s CVI diagnosis I made a mental list of all the places she regularly spends time (the crib, high chair, car seat, bathtub, etc.) so I could think of how to make those spaces more visually accessible to her (which you can read more about here). We were very home-bound when she was little, due to many factors relating to medical complications combined with my sheer terror when I thought about the possibility of her (or her big brothers!) getting sick that fall/winter/spring. But, because Rosalie has two big brothers we necessarily spent a great deal of time engaged in free play throughout the house.
We clearly have two spaces in which the boys regularly play, depending on what time of day it is: the designated play room (located upstairs) and the living room (located downstairs near the kitchen). These were the two rooms in which I would spread out a big baby blanket and create a “play space” for Rosalie as she grew, so the obvious next step after learning about her CVI was to make both of those baby play spaces easier for her to see. I really don’t think I had even learned the visual term “defined spaces” yet, but it made perfect sense to minimize the complexity of these spots where I would regularly lay her down with some toys.
The living room was pretty easy, because I had already naturally carved out a little safe space for Rosalie where her brothers quickly learned to stop running, slow down, and be extra careful (we had made strict rules early on about not getting on her baby blanket without asking my husband or me). So, all I needed to do was trade out the blanket for one that is solid black (which I purchased on Amazon). Then, I placed a black tri-fold “science fair” board near the blanket so we could minimize complexity while she was side-lying or doing tummy time.
Since Rosalie was 7 months old when we received her CVI diagnosis she had long out-grown our “real” baby play mat that came with hanging toy attachments, but her CVI meant that she really needed to have things hanging above her that she could practice looking at. She was not yet mobile (she had started rolling to her sides and a little bit onto her stomach), so having things hanging above one space where she could not move from was an important way to integrate vision into her play time.
