I was reading a book with my son. The illustrator draws a ladybug on each page to make the book more interesting. My son: I see a ladybug. Do you see it? Me: I don't. Could you tell me where it is? My son: Here it is! Me: Oh...You did see it. It is right next to the flower. I'm not sure if the tense in the last sentences are right. #1: "You did see it": because he saw it a few seconds ago, I used the past tense. (Sometimes he thought he found a ladybug which wasn't a ladybug.) After thinking about it, I feel #2 'you do see it' seems to be ok as well. Which one sounds more natural? How would you say it? Thank you. :)
