Nobility.org has an anecdote about Marie Antoinette's kindness and concern for a pregnant woman. To quote:
When the student realized that one of the ladies was the Queen herself, Marie Antoinette, he stood up in dismay, apologizing, and trying to justify his intrusion.
Filled with goodness, the Queen set him at ease, saying: “Look here, go and bring her quickly! I’ll make sure no one takes her place.”
When the expecting mother was about to sit down, the Queen called over a servant and said: “Go to my bedroom, and bring a cushion for this lady,” and then explained her gesture, saying, “Many cares are required when in your condition. This marble bench is too cold for you to sit down on.”
