DS is just 3 and I’ve been using makeshift blackout blinds his whole life - we have odd windows with angled recesses so I’ve been using stick on ones or similar for years. I’m so done with faffing around with them, so I have bought proper blackout curtains. Put them up and they left some light in underneath and round the sides. Please reassure me that my child’s sleep will be ok without them as I think they’ve been a placebo for a while now…
