If your baby has been having a fever for more than a day and the medication doesn't seem to be helping, it is recommended to consult with a doctor as soon as possible. Additionally, if your baby is having more frequent and watery stools, it could be a side effect of the medication being taken. Make sure to keep your baby hydrated and consider giving probiotics to help with antibiotic-associated diarrhea. Remember to space out probiotics and antibiotics by 2 hours.
