The recent one I saw that I thought shouldn't have been moved was the one about what age children learn they are going to die someday. The OP had a child who was almost 3, but she wasn't asking specifically about kids that age. It made sense to address the question to parents of older children who had already learned about death, not to parents of toddlers, who would mostly not have learned about it yet.
Yes, this was the thread that prompted my original question. Most children begin asking about death between 4 and 5. Some kids begin asking about it at age 3, however. As such it is NOT a toddler issue, and I doubt that parents of kids who haven't reached this developmental stage can have much to say about the issue.
On purely practical note, if you're going to make your poor moderators move threads based on whether content is relevant (rather than on just age), I hope they've got a really really good background in child development!
