Three month old babies with cold and runny nose need to be treated promptly by drinking more water, keeping warm and using pediatric cold flush and antiviral oral solution to improve the symptoms. Babies are weak and have poor resistance during infancy, so they are prone to colds and runny noses when they catch a cold. At this time, mothers should take good care of their babies and let them drink more water and urinate more often, which can make the toxins in the body discharged quickly and relieve the symptoms of the baby’s cold. At the same time, pay attention to the cold and keep warm to avoid catching a cold again, which can cause the baby’s symptoms to worsen. For common colds, you can give your baby Pediatric Cold and Flu Spirit Punch, a proprietary Chinese medicine that can treat symptoms such as sneezing, runny nose and cough caused by wind-heat type colds. If your baby has a yellow runny nose, it is mainly considered to be caused by bacterial infection, so you can take your child to the hospital for examination and take oral anti-viral medication, such as anti-viral oral solution, if necessary. During the treatment period, keep the air in the room circulating and moist, and often disinfect with smoked vinegar, which is beneficial to the baby’s recovery.
