What happened if a Monarch gave birth to twins? Is there an example of this happening and who would be first in the line of succession?

I've always been interested in monarchies across Europe and I've always wondered what happened to the line of succession when Monarchs gave birth to twins.

I assume it was a rare occurrence but surely it has happened before?

If it did happen, did it create rivalry over the succession of the crown, maybe even conflict?

Would the first twin to come out the womb be first in line, or would the Monarch pick their 'favourite' to succeed them?
