I had one who took 6 months!!!!!!! Parents were not on board for setting up similar 'parenting' styles and it REALLY affected this little one. I struggled and tried everything I could think of for 6 months straight. Now this little one is the perfect child and adjusted just fine. Took forever and not sure I would ever struggle that long again, but it did get better I can totally relate to how frustrated you are, there were days when I would just want to cry along with the little one. The others in daycare didn't like this particular child for the longest time because of the crying and even the parents would question it when they picked up their child and this little one was screaming bloody murder...my only suggestion is to be as stubborn as they are. I did all the coddling, the picking up, the telling it would be ok, and finally just got to the point where we would all ignore it and move on with our day. If she cried, she cried but we still did everything we had planned for the day...once I started to ignore it and the other kids ignored her it stopped within about 2 weeks. I really and truly believed she knew exactly what she was doing and got away with it at home..
