my daughter, Izabella is 10 months/8months adj. and is scared of any new people. She is fine until they try to touch her or hold her. Even with my father....we see him 2x's a week - and she still screams bloody murder if he tries to pick her up. The only people she will let hold her are myself, her daddy and her Nana. Is this normal? Why would she be so freaked out? Has anyone else experienced this with their little one?
