I do think we can make our own quite nicely.
“Baby Rabies -- When someone is desperate to get pregnant and have a baby, we call them having “baby rabies”. Especially if they can’t talk about anything BUT pregnancy and babies.”- happilychildfree.com on baby rabies [1]
“The name given to the lapse of sanity in which a person feels that s/he absolutely MUST have a baby in the very near future, and will often go to great lengths to get pregnant and will bitch constantly about wanting a baby in the meantime. Usually happens in women, but men get it occasionally, as well.”- urbandictionary:baby rabies
