So much depends on the situation . . . and you can't prevent him having big feelings, but you can actively teach appropriate reactions (in and out of the moment). If you don't mind giving him what he wants then I say give it to him and don't say no--if you change your mind when you realize how important it is (like if you were saying no because you didn't think it was a big deal but would be inconvenient) then take responsibility and say you are changing your mind. If you mean no then mean no and don't give in (that is what creates tantrums in older children
).
