My 3yo started a new nursery over a month ago. The nursery is lovely and he always has a great day and comes out smiling but he is hysterical at drop off. Sometimes from the moment he wakes up in the morning. It used to be when we arrived at nursery but now he cries the whole way there and hysterically cries when we arrive. I just don't know what to do to make nursery drop off a more pleasant experience for everyone. Any advice would be great! He never used to do this at the old nursery
