The best time for newborns to swim varies from individual to individual, and it is usually recommended to do so within half an hour to one hour after feeding, when the child is not hungry and has more energy to ensure a better state when swimming. Newborn swimming can exercise body coordination, enhance lung capacity and heart function, promote healthy bone growth, advance the development of brain nerves, and promote the establishment of normal sleep rhythms in children; it can also promote gastrointestinal motility and appetite. The baby is relatively quiet and not irritable between half an hour and one hour after eating milk, which is most suitable for swimming.
