DD is 19m and lately has had a few episodes of loose/runny nappies but not full-blown diarrhoea. She doesn't seem ill otherwise, but it's enough that her nursery asks that we keep her at home for 24hr. I'm wondering if it's because she's outside, digging in the garden, more than she used to be. I really don't want to protect her from all dirt and be brandishing antibac wipes all the time, and thought a soapy handwash before eating would be enough! Anyone else got the same problem? Any advice please?? Does it pass in the same way that the never-ending nursery colds did?
