My little boy has been attending nursery since the age of 8 months. We recently moved to a new area and needed to change his nursery. He is sick at least every other week and this has been happening for the last few months. It’s becoming a pattern and unsure of what to do. He is 3 years old now and is only attending the nursery for the social aspect and to ensure he doesn’t become unsettled when needing to have a routine when beginning school. We are getting sick of him getting ill. He has always been a healthy boy. Is there anything we can do?
