Usually, babies can be bathed once every 2 to 3 days, and the interval between baths is related to temperature, environmental hygiene and the baby’s own condition. 1. Temperature: there is a significant relationship between the baby’s bathing time and temperature. If the weather is hot and the baby sweats more, the frequency of bathing can be increased; however, if the weather is colder and the baby sweats less, the time between bathing can be shortened. In general, the environment temperature is suitable, about 2~3 days a bath can be. 2. Environmental health: baby bathing frequency and environmental health also has a relationship, if the environment is cleaner, about 2 days ~ 3 days to take a bath; if the environment is dirty, in order to avoid the baby to get sick, it is necessary to appropriately increase the frequency of bathing, in order to reduce the baby’s risk of illness. 3. their own situation: if the baby is full-term birth, the resistance is generally good, 2 ~ 3 days to take a bath, can ensure a good state; but if the baby is premature, usually weaker resistance, if often bathing, and the water temperature is not appropriate, may increase the baby’s risk of illness, so the interval between baths can be extended accordingly. In short, the interval of baby bathing is about 2~3 days, and the interval time needs to be combined with the temperature, environmental hygiene and the baby’s own physical state. In the process of bathing, it is necessary to pay attention to the water temperature should not be too hot, too cold, and because the baby’s skin is more fragile, so avoid excessive cleaning. You also need to dry off the water as soon as possible after bathing to minimize the risk of your baby getting sick.
