Hi Welcome to the HCM I understand your concerns but don t worry. Young infants do show many changes in frequency, consistency and colour of poops. It s perfectly fine if she if on exclusive breastfeeding. You should just feeds her regularly. Give her both the fore milk and hind milk. There are antibodies in breast milk which can handle mild infections of the gut. If you are giving her formula feeds, then follow these measures: 1. Take a proper care of hygiene while preparing feeds. 2. Go for a stool examination in laboratory if loose watery stools persistent or the amount increase with associated fever. If infective diarrhea, then antibiotics may be needed. 3. For mild fever episodes, you may give her acetaminophen drops. 4. Keep the diaper area open to dry for some time at each change of nappies. 5. Apply petroleum jelly lightly before putting on the diapers. If rashes are severe, you can use diaper rash creams available OTC, such as rashfree. 6. Offer her frequent feeds to avoid dehydration. Hopefully she will be fine. For further questions, you may contact me.
