V.P.
My daughter did this all the way into third grade. She'd do it now if crying was more accepted among her friends (fifth grade). She is very bonded to me and has a lot of anxiety, separation anxiety being just one form. She still wants me to walk her to her room at school instead of dropping her at the door. She is very uncomfortable asking for ketchup packets at a food counter or going to ask her teacher a question if I'm anywhere nearby. She is smart, has a lot of friends, and is very pretty, but doubts herself constantly. I don't have good answers, but just be prepared -- it could be a long ride.
