At 11 months he's just reacting -it's not so much of a tantrum. Wait until he's 20 or 22m! THEN you'll really be getting into tantrumville! When he's older, ignoring is a good tactic! At his age, just pick him up and love on him and see what the fuss is about -dirty diaper, hungry, etc. He's just expressing displeasure in the only way available to him at 11m. When he gets more verbal, encourage him to "use his words" instead of acting out.
