A recent question has become a duplicate of What should I be teaching my two year old? which is now quite old and was probably OK at the point of being posted. The question as it stands now however appears to be off-topic for Parenting and would normally be closed as either too broad or primarily opinion based.
My question here is what do we do on Parenting to such questions when we come across them? Should I cast a close vote on such a question?
On Stack Overflow, where I spend most of my time, such questions are closed. In some cases they are downvoted, especially if the question has been brought to META for clarification. What I don't want is for the question to receive downvotes due to the META effect. That isn't my goal here. I just want clarification on what we do here with old, off-topic questions.
