Toddlers no, annoying visitors, YES!!! why not! Annoying visitors think it's alright to tease their host/ess, prank them (despite the antiprank hack) and generally annoy them - slapping would serve them darn well right!
Oh, and there is a nojumponbed hack which was recommended in a thread here and works really well, haven't had a kid do it since I installed it! I think it would even stop Lucy Burb, though I can't check now, she's about to graduate! Sorry I can't remember where it came from, but I think a search would find the thread and the link.
I gotta try that bed jumping hack. I have alot more kids now then when I first saw that thread you mention.
Well, I don't exactly advocate toddler abuse, but last night I had to know what would happen if i had an adult attack a toddler. The fight, the thought bubbles afterward, and the toddler waking the next morning with the want to see the ghost of his mother were pretty hilarious. The first use of the attack hack was to have Nina Caliente slap some townie who wouldn't stop pestering her toddler. Loved that moment.
