Umm, I've read that teenagers are chronically sleep deprived. ANd how did you feel when you had a newborn?
Seeriously, you can have the odd night out and then just use the next few days to catch up on lost sleep. As you Lo gets older you can manipulate naps more, like having an afternoon nap that finishes at 5pm so you can go out and have a bedtime of 9pm, just as a one off. In a few more months things might start getting a bit more flexible, depends on what your LO's personality and sleep needs.
