In a previous post I'd noted that something called “blue chux” (AKA “disposable pads”) are a wonderful gift for new parents, who despite being told numerous times do not fully appreciate how much and from how many places babies can leak and otherwise expel bodily fluids.

Recently, I'd sent a case of them to a friend who'd just had a baby, and a month later he wrote me:

By the way, the disposable waterproof sheets are, by far, the most useful baby gift. Thank you thank you for sending them. I didn't know that babies are capable of projectile pooping and mischievous peeing.

Projectile pooping and mischievous peeing – things that all parents become well aware of, but non-parents know little about. :-)
