My dd1 (5.5 and yr1) came home from school yesterday saying that x is now her boyfriend. She seemed quite coy and shy about talking about it and made me promise not to tell her dad! My first reaction was that it was sweet and completely harmless, but then I started having a bit of a wobble about them growing up too quickly. Does anyone think I need to be concerned? Do they get upset if they "split up" - argh - Am I seriously overthinking this?
