LO has just started preschool, not been to nursery before so I expected she'd pick a lot of bugs up. Last weekend she was sick just once but off for 2 days where she was fine just very tired. Back in Wed and then has been having very loose stools since Thursday. Once a day apart from today when she's been twice. Her tummy hurts before it happens. She's also full of a cold which came on last night. Does this sound like a tummy bug or something else? What's the best thing to be giving her? We're trying to keep her fluids up and have got some dioralyte. TIA
