Kelly, Abbey went through this not long ago. It lasted about 6 weeks for us and was hell. I had to take time off work and fly my MIL over from Adelaide to help out.

We found that Abbey getting some quality 1:1 time with me and Grandma (she had 1 day a week out of CC and spent it with Gran) really helped. In the meantime, we carried her into the centre (she was making herself a dead weight and dropping on the floor when we got in), ignored tantrums in her room (which we do anyway), and encouraged distraction techniques. I had a word to the carers and Director so they would also help with distraction. The best thing that worked for us was getting her to watch for us through the windows into the corridor and wave goodbye. There is also a BIG window in her room which overlooks the road intersection - so we got her to stand at the window and we'd wave from the car. Not a tear or tantrum to be seen! We also noticed she was worse when we dropped her into the combined room in the mornings - so we try to drop her off after that has ended and if it is earlier, they try to get her into her normal room ASAP. She is a LOT better now. Back to being her normal happy self and loving child care - she runs in and is all smiles. Waves us off and gives us a huge kiss. It is wonderful.

Hang in there and follow your heart.
