My latest project is a baby bassinet mobile. My friend and I made some black and white sheep out of felt to hang over the bassinet. I got the idea after looking at black and white mobiles on etsy. Those crib mobiles are super cute but also seriously expensive. The sheep mobile will replace the owls that came with the mobile on my pack n play playard bassinet.
I choose black and white sheep because apparently young babies cannot visually process low contrast colors. So all those cute pastel colors and toys probably look like boring blobs to newborns. High contrast black and white (with some saturated red thrown in for good measure if you want) is easier for babies to see and may aid in infant brain development. As babies get older the ability to distinguish more subtle colors improves (duh). Small for Big notes that black and white baby mobiles might not be the best choice for a crib, because they are stimulating and not relaxing (i.e., sleep inducing).
Of course, it doesn’t make sense to me that babies absolutely need special black and white accessories to improve vision and/or cognition. I bet babies have got along just fine for hundreds of thousands of years without black and white mobiles.
I decided to keep this craft project simple. If you are feeling more ambitious, Life Sprinkled with Glitter has some cute ideas for baby mobiles that you can make yourself. To make my simple sheep mobile, my friend and I made sheep shapes and cut out the piece from some cheap felt. We sewed the layers together, then stuffed the sheep with cheap polyester fiberfill. The whole thing can cost just a few dollars if you can keep your fiberfill cost down. But keep in mind that this cost is simply for the sheep, not a mobile frame to hang them from.
