And if so, how the fuck can I persuade them to stay put?
They are 22 months, in beds because they were climbing out of cots. So I spend an hour or more sat between their beds in the dark, grabbing each as they make a run for it, and putting them back to bed. Which they find hilarious. Bedtime routine changed when we got beds as I am no longer feeding to sleep, but first week of beds they were asleep by 730. Now it's nearer nine. They're still up before 6, so getting increasingly tired and grumpy. As am I.
