I don’t get my toddler water when he says, “I’m thirsty.”

Ok, I know how that sounds, but before you think I’m a mean mom, hear me out. When my toddler says “I’m thirsty” I don’t jump up and get him water. Instead, I say: “Hm…what can we do about that?” (honestly sometimes I say “so what” lol) And then I wait.
