Sleep Like A Baby

Going to sleep last night, my DH & I had a discussion about the phrase "sleeping like a baby". Why is it that we say, "I had a great night's sleep - I slept like a baby"? That's supposed to mean, "I slept well, I slept soundly, and I slept all night!"

Every mother of a newborn will tell you that babies wake up throughout the night!! Waking up throughout the night is one of the hardest parts of being a new mom !!

So I've always been puzzled by the phrase. I'm sure the phrase refers to the way babies can fall asleep anywhere, and sleep through the strangest circumstances. But it's still a funny phrase!

Thankfully, I slept 'like a baby' after all that talk about sleeping and not sleeping!
