When a baby has a cold, their physical condition is not at its best, which means their physical ability will definitely decline. Under such circumstances, we do not recommend that the baby goes swimming. Swimming can increase physical exertion in the water, and sometimes the water temperature is not properly controlled, which could potentially increase the baby's burden. Especially when there is significant physical exhaustion, and if the water temperature is not well controlled, it may worsen the baby's cold symptoms. Therefore, we advise against swimming in this situation, but you can still give the baby a warm bath. However, make sure the duration is not too long, and the external temperature must also be appropriately managed.
