This recalled a childhood memory. When I was extremely young my first words were 'mum' and I used to refer that for thirst. So mum meant 'give me water' and since mother used to be around, she was the one to provide it. Or it could be that mother taught me to associate 'mum' with water as that was the word I could pronounce first. Hmm..
