Howdy, sorry to hear about your friend finding it hard to understand where your dd is coming from. No, of course, reading before 2 is totally not normal. Maybe you're downplaying too much!
Your daughter sounds like a delight and a handful; we are not in pg territory with our kiddoes but they are still sort of a puzzle to others. One of the funnier things we ran into from other folks was getting various 'diagnoses' from them as to ds 'problem'. Maybe this is more common with high-energy boys than girls, but it was pretty amazing to hear the first few times, though I say 'funny' now.
Good luck to you and welcome!
