I hear you playfelt. My two 16 month dcg's have been with me 21/2 months and still get angry if I leave the playroom to get snack or heaven for bid, go to the washroom. Yesterday, I did an experiment where the girls were left with my sweet dcb's who are 3 in the playroom while I sat on the stairs at first so I was visible but not available to entertain. The girls were really pissed and let me know it for 15 minutes and then their attention turned to what the boys were doing. I sat another 5 min and watched them play and then I went upstairs. The crying started again. After 5 min I went on the stairs and reassured that mimi was getting snack and went upstairs. I got another 8 minutes of hellfire crying and then they stopped and went to play. It really was excrutiating to hear these lovlies be so angry with me, but it was time to learn to play on their own. When I return, it is all big smiles and no evidence of tears so I know it is just anger and not fear. It's a start.
