The short version

  • Real darkness supports better, longer sleep for babies and you.
  • Most off-the-shelf blackout still lets in light at the edges.
  • A portable blackout blind is worth its weight when you travel.

Blackout is not glamorous, but few small changes make as much difference to sleep. Light is the body's strongest signal to wake, and the early-morning glow through a gap in the curtains can end a nap, or a lie-in, before it has begun.

Why it matters

Darkness supports the natural sleep hormones that help everyone settle and stay asleep. It is especially useful for daytime naps and for the bright early mornings of a British summer, when 4.30am light can quietly undo an otherwise good night.

Getting it actually dark

  • Mind the edges. Most light sneaks in around the sides, not through the fabric.
  • Layer if you need to: a blind plus a lined curtain.
  • A portable blackout blind travels well and saves many a holiday nap.

Test it in daylight. If you can comfortably read in the room, it is not blackout yet.

Bubba & Me tip

Stand in the room mid-morning with the blind down. The gaps you spot are exactly the ones waking your baby at dawn.

Blackout supports sleep, but always pair it with current safe-sleep guidance for naps and night-time.
