Our 2.5 year old daughter started her nursery in October. However, the problem with her is that she would have a cold for half of the winter months (so 6+ weeks), and the nursery obviously doesn't allow ill children. What do people do in these cases? We can't take 6 weeks off work just to stay at home with her.
Most nurseries don't kick kids out for a cold or cough as long as the child does not have a fever, however if your nursery is you can take your daughter to the doctor and get a note saying she is okay to go to school. Most doctors will write a note for a child with a cold, as colds don't go away for a long time.
