When a child is young, it is easy to get sick because of poor resistance. This situation will get better when the baby is older, because as the child grows up, his body becomes stronger and his adaptability to the environment will be greatly improved, and he will not feel sick because of a little anxiety.
If the child is always ill at his parents' house, he can wait until the child is older. If the elderly miss their children, they can visit their own homes. Now most of them are only children, so it's normal for their parents to go to their daughter's house. It is easy to get sick, which also shows that the baby is in poor health, so we should pay more attention to life, supplement nutrition for children, increase physical exercise and so on.
