A metaphor that literally means a person slept peacefully throughout the night.
Most people today do not know how to take care of babies, as a result their child wakes up every 2 hours, pissing and crying and have incorrectly interpreted the meaning of the expression to mean: "Slept like the hell spawn of Satan".
I say hell-spawn of Satan because only Satan could treat a child as badly as these people treat their own children. But fear not children of God, for the age of darkness will only last a short 1000 years.
Something someone says as a metaphor, but what they don’t realize is babies wake up crying every 2 hours for food or a diaper change.
Person D (D for dumb): Man I slept like a baby last night
Person C(For common sense): Babies sleeping schedule is very unorganized cluttered and they wake up randomly
(Now that I think about it the saying is kinda tru abt me lmao)
When ABDL, babyfur, DDLG or littles go to sleep wearing a diaper, snuggling plushies, sucking on pacifiers, experiencing peaceful bliss and being adorable
I put on a PeekABU, grabbed Stitch and my paci and slept like a baby.
