। ॥ ३८ ॥
In plain words
A son is won only through hardship after hardship on the body and wealth poured out. And the moment he is born, the worry over whether he will live weighs heavier than all of it.
Close to the Sanskrit
Through various bodily hardships and through expenditures of wealth, a son is obtained. When the son is only just born, the anxiety over his living is heavier.
