My son nearly 3 years,started nursery in September we had a few issues with settling in but seems to be ok however I have been turning up at nursery to find him soaking wet having wet himself on three occasions now, he is also started to wet the bed and is having a few accidents at home, not sure if I'm being over protective but worried about him being anxious. Nursery are doing a full investigation as to why no one has noticed that he has wet himself. Any advice? Thanks
