DD aged 3.4 has been clean and dry for over a year and since December has been dry at night. She started a new nursery a few weeks ago and since then has had several accidents. Most of the time its wetting herself which I put down to her leaving it too late to go to the loo. This morning and last week she has pooed herself as well. She says she is happy at her new nursery (goes every afternoon to a pre school at a local primary). I have told her she will be taken to the loo every hour and have gone back to putting a star on her chart when she goes to the loo. Should I take this as a stage she is going through or a sign that she is unhappy at nursery? Any ideas how to deal with this? Thanks
