A good response to a coworker who asks, "So…you have kids?" depends on your personal preferences and comfort level with sharing personal information in a professional setting. Here are a few possible responses:
Polite but private: "Yes, I do. They're an important part of my life, but I prefer to keep my family matters separate from work."
Casual and friendly: "Oh, yes! I have [number of kids] wonderful children. They keep me busy and bring so much joy to my life."
Humorous deflection: "Haha, well, my kids are actually my two furry cats at home. Does that count?"
Professional and non-committal: "Yes, I have kids. How can I assist you with work-related matters?"
Turning the conversation back to them: "Yes, I do. How about you? Do you have any children?"
The key is to respond in a way that you feel comfortable with, keeping in mind the context and relationship you have with your coworker. If you prefer not to share personal information, it's perfectly fine to politely deflect or steer the conversation back to work-related topics. Remember that it's okay to set boundaries and decide how much personal information you want to disclose in a professional setting.
