My daughter is almost 2.5. Today we were out for lunch when a woman at a nearby table looked at and/or smiled over at her. She immediately got really upset and started shouting "that's my mummy, don't steal my mummy" and looking over at me as if she was really scared/worried. This has happened before where maybe we will walk past someone in the street who doesn't even look at her and she'll get angry and upset and tell them the person with her is hers eg "that's my auntie/gran/daddy".
Has anyone ever had their child behave like this before? I'm not really sure how to deal with it and she got so upset today that I actually thought we might have to leave the restaurant.
