I heard a similar playground conversation to your LLL meeting debate. Two
Moms were discussing their babies. One slept through the night, one had
such terrible sleep problems and didn't. Mom #1 considered sleeping through
to be from about midnight to 5 am. Mom # 2 thought her baby didn't sleep
through because she woke at 9, midnight, 5, and 7. It turned out that
actually the babies had pretty much the same sleep/wake pattern!
