My 3 month old has been sleeping in this bedroom that has blackout shades, but a ton of light comes through the gaps between the shades and the frame and wakes him up. I can’t figure out how best to make it blackout in here without replacing the shades. I thought black weatherstrip tape would work but it doesn’t block the light. And I’m not sure I can put up curtains because the window frame runs all the way to the edge of the wall on both sides. Any advice would be appreciated!
