Hello; my daughter is aged 3 and for the last few days has been passing liquid poo in her nappies. Occasionally she will pass a normal one and I think that everything will be OK, but then she will go back to passing liquid again. She has no tummy pain, and it does not cause any burning sensation for her as it passes. She hasn't been vomiting. She is slightly underweight for her age but I'm not sure of her exact weight at the moment. She likes milk, fruit, bread, spaghetti, cereals, vegetables, cheese and some white meat but not red meat. Her diet hasn't changed recently. I've been reading about toddler diarrhoea; will this just go by itself, and should I be giving her something to help firm the stools up again? Or take her to see the doctor? Thank you.
