DD is 2.7 and has been going to the same nursery since she was 1 with no issues. For the past month she has started crying in the car and really really crying before going inside. Nursery have asked us if anything has changed at home (it hasn’t) as she seems to be upset every morning for 1.5 hours and won’t say why. She is fine at home and at her grandparents. When I ask her what’s wrong she just repeats the question. Any ideas or tips?
