Give her time and make sure every interaction you have with her is fun/enjoyable for her - NO PRESSURE. Also don't make the sessions any longer than about 10 minutes - you need to be the one to walk away first - take it from me that's VERY HARD to do!!!
Pretty soon you'll have a paddock schmooze like the Zeph Man whom you can't get away from. (he has now started to whinny out to me - an hilarious little girly squeel)
