Yeah, this is one of those quotes that is cute/clever... until you have kids and learn or experience how common 'latching' problems are.
It's pretty distressing to watch the desperation and the struggle of a baby screaming and a mom trying but unable to feed her baby.
Then the quote sort of turns from clever into a sign of a bit of real-life ignorance.
Yup. Horny teens can figure out their genitalia combo much easier than many infants figure out latching
There's a deeply ingrained mythos around how natural and easy motherhood is, but in nature, a lot of first time mothers are rather mediocre. It takes a while learn how to do all those "natural" things like nursing the baby.
And let's not forget that babies kinda suck (intended) at doing "natural" things too.
