Whenever we went out when the kids were babies, they would just sleep in their pram, and luckily for us they would settle easy and it didn't put their routines out at all. Even if you did go out occasionally and Paige didn't get to sleep on time, it is only one night kwim? If you go to your IL's you would be able to put her down on a bed or something in a quiet room so that she can sleep.
