I've heard the reference to female babies, too.

You're right! I've heard male babies called "little man", too come to think of it.

I second the cringe factor. Perhaps I cuss too much? Because any word resembling "mother" directed at me by someone who I did not give birth to - has a whole different reaction. I think of mother-you-know-what!

I understand that it may be a cultural issue - but then, that's MY cultural way of thinking as to what the word connotes. Best to just stay professional in a business setting in my opinion. Save the nicknames for family gatherings.
