This is one of the great shared experiences of parenting. Almost everyone I know has this same reaction the first time their baby sleeps longer than a few hours.

And the thing is, it doesn’t go away! Just a few weeks ago, Momo was resisting going to sleep, until finally she just… stopped making noise. OF COURSE I had to go in and check on her. And of course she had just finally fallen asleep, which was exactly what I had been waiting for. But that little worry remains.
