Wish you good health. Do you use a period or an exclamation point?

Healthy and happy growth! Use exclamation mark, because it belongs to the greeting. Generally, greetings are exclamation marks, expressing sincere wishes, just like when the baby is born, and then the congratulations sent by relatives and friends are like this: I wish the baby a healthy and happy growth! This is also the wish of all parents. It is best to be healthy and happy when a child is born.
