I bought Hippy chick dream tubes off eBay and it works great! Essentially a sheet that has inflatable rails on the sides.
DO NOT GET A RAIL! They’re so dangerous! I learnt this the hard way . Have a look at alternatives
@Katie good point. I remember the video of Milo flipping over it. If possible, @Joanne put the mattress of the single bed on the floor.
@Lee honestly one of the worst experiences of my life!
@Katie oh my goodness! I remember seeing that video! Hope your little ones okay now. That’s absolutely terrifying!
@Joanne he’s fine thank you but the boy doesn’t learn 🤣 his new favourite thing is to scrunch his duvet up at the end of the bed then run and dive into it 🤦🏼♀️ he laughs his head of but I’m waiting for the day he runs just a little to far n hits the headboard
I don’t have any bed rail recommendations, but if you can’t find anything suitable - my little ones sleep on these when we go places https://amzn.eu/d/5NkAit1
