My son is 9mo he goes to nursery on the days I work. I explained yesterday that he has had loose stools but doctor has said he's fine, caused by change of diet and teething and having the cold they said it was fine at drop off. When his dad picked him up they have told him he can't come in for 48h after last loose stool? He's absolutely fine I explained he's been having them for the last few days so can't see them leaving in 48hr. He has no fever, eating as normal and has no sickness. Is this normal procedure for just loose stools accompanied by no sickness or fever ?
