My daughter (15 months) has had diarrhoea/ loose bowels for about 2 weeks now, going several times a day and always runny and smelly. Was just putting it down to teething and the fact she eats like a horse at first but starting to get a bit concerned. Spoke to my Dr who said to put her on a bland diet for a few days and see if that helps. But last night she did this poo, someone told me black tarry poo can indicate bleeding so I went down to the Drs and asked if I could have a sample pot for it but they can't send it off until Monday and I can't stop stressing about it. There's obviously lots of mucus too. Should I be worried? What could be causing bleeding if there is any?
