If your 13-month-old child has been irritable recently after being sick, there are a few things you can do to help them recover and improve their overall condition. It is common for babies to be a bit more irritable after an illness. If your child still has a runny nose, it is recommended to use a saline solution like Hydrasense or Salinex for nasal hygiene. This can be done as often as needed during the day and at least 30 minutes before bedtime. In addition, if there are any unusual skin lesions or other concerning symptoms, it is best to consult with a pharmacist or healthcare professional for proper guidance. Remember to monitor your child's symptoms and seek medical advice if necessary.
