The middles wanted a sleepover in their room last night. Amelia isn't allowed in Matthew's bed because she isn't six yet and we do not allow kids under the age of six to sleep in the top bunk.
Matthew isn't keen on sleeping in Amelia's bed because he's worried that she might pee the bed (not an unreasonable position, tbh).
So we put mattresses on the floor and told them that they needed to actually do some sleeping or they would not get to do it again anytime soon. There was a LOT of giggling and chatting but eventually they did fall asleep without too much fighting for once.
