English to Spanish Art/Literary Religion 19th century book about Christian mothers

Your child has been, during the day, very pleasant and obedient. Just before putting him to sleep for the night, you take his hand and say, "My son, you have been a very good boy today. It makes me very happy to see you so kind and obedient." This approbation from his mother is, to him, a great reward. And when, with a more than ordinarily affectionate tone, you say, "good night, my dear son," he leaves the room with his little heart full of feeling. And when he closes his eyes for sleep, he is happy, and resolves that he will always try to do his duty.
