Small children are likely to lose their appetite for many foods during colds and fevers. Because watermelon is cooler, it is likely to want to eat watermelon, but it is best not to give him food. Because a child’s gastrointestinal function decreases during a cold or fever, his appetite decreases as well, and he doesn’t want to eat a lot of things he sees. At this time it is best to give the child to eat warmer food, too cool watermelon is likely to lead to a further decline in gastrointestinal digestive function, serious and may even lead to diarrhea. If the child’s appetite has not significantly decreased, gastrointestinal digestion is very good, not very picky about food, then you can eat 1-2 mouthfuls of appropriate, tentative attempt. If the child does not have any uncomfortable feeling after eating it, you can feed him 1-2 more bites at the next meal, but the amount of food should not be too much.
