We are planning for a natural birth - although I won't be heartbroken if plans change - and our childbirth instructor recommended I labor at home as long as possible.

What did you do while you were in early labor and not yet at the hospital? A couple of my friends who labored a long time at home have volunteered to come over and help distract me, which will be AWESOME... but I don't want to call them if it happens at, say, 3 a.m. What helped distract you and passed the time?
