Parenting may not come naturally to everyone, but occasionally common sense dictates good child-rearing decisions. For example, it's generally frowned upon to bring your infant daughter to a party at the Playboy Mansion.

Hint hint, Kelsey Grammer.

This weekend, the actor was spotted celebrating at the annual Playboy Halloween party until the wee hours with his 3-month-old baby, the innocently-named Faith, swaddled in a bassinet nearby.

Dude. Don't you make enough money to hire a nanny? Don't you have any friends who'd be willing to babysit? What about your wife? What about your other children who now have their own children because you keep marrying women half your age?

A source noted that at midnight, Grammer was enjoying himself at a table near Paris Hilton. We're hoping she didn't use her barely there 'Alice in Wonderland' get-up to tell Faith any bedtime stories.

Meanwhile, one of the Playboy playmates proved even she has better parenting instincts than the 'Frasier' and 'Boss' star, tweeting, "Why the f**k does Kelsey Grammer have a newborn baby at the Mansion party!?!?!?"

The world may never know, but we wonder if it has anything to do with his fascination with Playboy models, most notably his sexless ex-wife -- and former playmate -- Camille Grammer.

Or maybe he just thinks it's never too early to set his daughter on the path to (naked) greatness.
