Tell the parents to maybe try saying their goodbye's in the car, or while they are walking up to your door and to do the separation as fast as possible at the door with a quick bye as they hand her over. If they stand around to comfort her, it will make it worst. And if she knows they will react to her, she will continue and her separation behaviour will get even worst. Important thing is for them to not react at all and have the same matter of fact "see you later" no big deal attitude. Once she experiences that, she will calm down if she see's that they are calm....even if they are nervous inside. They can't show that to her. And once she's inside I would make sure to always have something fun and new ready for her to experience to distract her. If that doesn't work, I would firmly say "*name of child*, this is not acceptable. When you act and cry like this you are scaring the other children and we don't like to see you like this. If you need to cry you can sit here (place her aside from the group) and you can come and join us when you're ready"....but then I realized that you wrote she was only 1, so she probably won't be ready for doing the latter part. In this case I would make sure to go with the same quick separation, distraction with something fun, and lots of holding and carrying around for the first few days until she starts to settle down. Once she starts to feel comfortable, continue to do activities close to her and very slowly start to teach her that if you leave for a second its ok. She might fuss, but just always remind her that you are just going to get this and that beforehand and that you'll be back in a second. I had one child, 1 yrs old, who screamed when I walked to the other end of the room for a while. And now she's totally part of the sphere. I had to firmly always tell her that no, we don't need to cry, everything is ok, nothing bad is happening, I just need to grab a toy for so and so. After a few weeks she was totally settled in, but then got sick, left for a week, and came back and I had to do the same thing all over. They just need to feel safe, loved and be reassured. Once they get there it is sooo nice....but definitely stressful until then, but it should pass.
