True em but I know for my little ones, particularly my DD, if she gets a cold she can have a sniffly nose and cough for up to 6 weeks in mid-winter and I cannot keep her home for that time. SHe is essentially over it but has that lingering cough - having said that she can wipe her own nose and so can DS so as 3LM said, when they were younger they couldn't and I was home a lot more with them. You can check with your carers about what they feel is appropriate too - I am talking child care moreso than kinder here so might be different strokes for different folks.
