Well... you could see what is provoking her becoming totally overwhelmed and seek to avoid it.
Not 'ooh, if we don't do this exactly the right way, she'll flip out' but 'when she's overtired, too hungry, thirsty, in need of affection and attention she loses her ability to deal with the world and has a meltdown.'
Find the cause, so you can remove it. Too many rules? Too many expectations for a child this young? Not enough food? Expecting her to follow a moving target (because the ability to walk doesn't come with the ability to walk toward something that changes position --see lots of overwrought children in the mall with parents who clearly don't know that)... too many locations or events or people in one day (small brains can't handle our modern, busy worlds all day.)
A child who is fed, rested, watered and held close will have a fraction of the number of tantrums as a child who is in need of any of those things.
