Sharing books

We’ve changed bedtime routine recently.
Rather than us choosing story. The children are bringing two books each to share / read and talk about.
Awful unsettled night with Wom
How do you get a 4.5 year old to not wake up at 1:30 wanting to chat about tractors or at 2:30 telling you it’s dark or 3:30 to tell you how many stars are on the clock or at 4:30 signing nativity songs at full volume?

Long day
Grumpy. Tired. So much work to do
