<s>[INST] My 10 month old baby will not take her formula anymore and have been advised not to give cows milk just yet as her tummy isn t ready for it yet. So instead I have been giving her soya milk for now until she is 12 months old for the cows milk. The only problem is that her stools are very loose and sour smelling. She doesn t seem to have an upset stomach but her poor botty is getting sore because she has become very regular in filling her nappy. Can you help? [/INST] Hi...It seems your kid is having viral diarrhoea. Once it starts it will take 5-7 days to completely get better. Unless the kid's having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. Regards - Dr. Sumanth </s>
