Dd is not yet sleeping reliably enough for it to matter, but sooner or later I presume I'll be wanting to keep the bedroom dark for as long as possible in the morning. What are the best ways to keep ALL light out? With dcs 1 and 2 we used blinds, curtains, cardboard, sellotape and anything else that helped after finding that even the smallest chink of light had a big effect on wake up times. This time I'm hoping for a more straightforward solution. We have quite large and long windows. Thanks
