The symptoms of a cold are different for each baby. Generally speaking, even if your baby has a cold before 6 months old, the symptoms are usually not very serious and the temperature does not exceed 38.5℃. The most important symptoms are runny nose, congestion and sneezing. Older infants have significant systemic symptoms, with a rapid onset and a tendency to develop high fever, cough and reduced milk supply. If the body temperature is too high, febrile convulsions may occur, so care should be taken to control the body temperature. The duration of the flu is usually 3-7 days, during which parents should take good care of their babies and pay attention to their observations. If the symptoms gradually worsen, it should be ruled out whether there are other diseases or combined with bacterial infections. Reminder: You don’t have to take cold medicine every time Cold symptoms are relatively mild, sometimes you don’t need to take medicine at all, let your child rest well, ensure sleep and drink more water. 1. Cold triggers nasal congestion When a baby has a cold, he or she will have nasal congestion. At this time, the baby will find it difficult to breathe while feeding, eating and sleeping, so he or she will make a lot of noise. At this time, the mother should clean his nose before feeding and nursing the baby. If there is no nasal blockage, it is congestion of the nasal mucosa caused by edema, cleaning the nasal passage is not effective, then the baby’s nasal root should be hot compress will make him much more comfortable. In this way, the baby will not be so annoyed. Blowing your baby’s nose should be noted: you should first press your finger on one side of the nose to blow the snot out, and then switch to the other side. Do not blow both sides at the same time to avoid damaging the eardrum. 2.Fever caused by cold More than 90% of colds are caused by viral infections, unlike fever caused by bacterial and mycoplasma infections, fever caused by colds manifests as persistent high fever. Generally speaking, the effect of using antipyretic medicine is not very obvious for fever caused by cold, so the fever reduction should be carried out slowly, as long as the body temperature is controlled below 39℃ to prevent heat shock. Another characteristic of fever caused by cold is that the temperature may rise again soon after it is lowered, so you should not rely too much on drugs. When taking antipyretic drugs, you should pay attention to water and electrolyte supplementation, and alternate between oral antipyretic drugs and physical cooling measures. When the fever caused by a cold reaches its course, the body temperature suddenly drops to a normal temperature, and the disease improves and is not easily repeated. In contrast, the temperature of bacterial infectious fever falls gradually and slowly, and if antibiotics are withdrawn before the infection is controlled, the temperature tends to rebound. If a cold and fever persists until the 4th day and there is no trend of decline, ask your doctor if you need to take antibiotics. Don’t take too much fever-reducing medicine: without other illnesses, infants don’t feel very uncomfortable. Even if there is some fever, the spirit is good and there is no delay in feeding and sleeping, and it will get better in a few days. There is no need to take too much antipyretic medicine. 3, cold caused by diarrhea baby cold, often accompanied by vomiting, diarrhea and other gastrointestinal symptoms, this may be because the virus attacked the intestinal tract, or because of the cold when the digestive function is reduced. Therefore, if your baby does not want to eat milk or food when you have a cold, do not force your baby to eat, otherwise it will increase the burden on your baby’s intestines, leading to indigestion, bloating and diarrhea. When your baby has diarrhea, do not give your baby abusive antibiotics. In this case, you should give your baby dietary modifications, such as extending the time between feedings, reducing the dosage of feedings, and changing the diet. When parents take their babies with colds to the doctor, most doctors will prescribe antibiotics, but this does not mean that your baby has a bacterial infection, it is probably a preventive medicine. As a result, there are many parents who think that if their baby has a cold, they should be given antibiotics, and this results in antibiotic abuse. Don’t take antibiotics as soon as your baby has a cold unless the blood test shows that your baby has a bacterial infection. If the fever lasts for 3 days and does not tend to go down by the 4th day, or if the cold is followed by severe coughing, wheezing and poor spirits and appetite, you should consult your doctor about taking antibiotics. In the process of using antibiotics, parents should not change and choose antibiotics on their own, at least after 3 days of taking them for their baby, and only when they think that they are really ineffective against the current infection bacteria, they should change the medication under the guidance of the doctor. Misuse of antibiotics will make the baby resistant and will make the antibiotics more and more advanced, which is not in any way beneficial to the baby.
