I have babysat for my two London grandchildren from the age when they woke once or twice in the night and sometimes said I'd do a "night shift" just to give my daughter and son-in-law a break when they were far too tired to go out. It's disruptive but only one night. I couldn't do it every day the way we had to when raising our three. It brings you closer to the babies so I hope you have a lovely sleepover.
