I was going to ask that too - how does she go once she is there and you have gone? Jack was 2 when he did this same thing for a few weeks. It didn't last long luckily, because as you say, it is an awful feeling for us when they do it. In Jack's case, he has always loved day care, but this happened after Tom was born (not straight after, but soonish after), and I think Jack missed Thomas. He would be fine after I left him, in fact the girls would always say he'd had a great day, but before hand he'd say "mummy, turn around and go home, don't want to go to kindy" etc. And mostly he'd cry when I left him, but then stop before I got to the door (I was out of sight by then). I think he wasn't that upset about going, but didn't like the idea of Tom being at home without him. Now Tom goes to day care too and they both go off so happily. I notice your 3 yo has a little sister too - is she in day care too? Anyway, I hope it passes soon for you, and hugs to you in the meantime.
