Some things that have helped us with the tanties are explanations as to why something is not ok, avoiding saying no and don't all the time, redirecting, keeping her busy with different activities, making sure she's not hungry, tired, teething is a big cause of tanties in our dd. Picking your battles too, some things are best let go. I can't see how old your ds is as I'm on tapatalk but it will pass, try to look at it as developmental.
