Yes, Brooke does already have window treatments. In fact, they are beautiful and we love them!
The issue is, they let a glow of light through. I didnt think this would be an issue, but when she started waking up the minute the sun rose I realized it was a problem. We looked into putting roller shades (or some sort of room darkener) behind the curtain ... but there isnt room! There isnt anywhere to hang another layer of curtain :( Thus, the aluminum foil solution.
