Anyone else's child 🤣

I thought I'd dodged the why phase with the youngest but oh no. We have mummy's what's this mean? Even when he knows the answers I say you tell me first he goes no mummy tell me for example "what's polo shirt mean " he knows as he's wearing this item. Another 1 is "what's ghost mean" and many more 🤔 🤣 is it just mine i should let you know he's 8 and audhd.
