How to stop a toddler tantrum before it ever begins...
Here's the actual truth, you can't. HOWEVER, I do believe that you can equip your child with coping and self-regulation skills to where a tantrum is a quick and relatively painless process. Tantrums are developmentally appropriate for toddlers as this is a time in their life when they discover their autonomy and that they're an individual in a big, big world.
But that doesn't mean your child should be miserable and fighting with you all the time in this crazy power-struggle. It starts from day one and it starts with you setting them up for success. The tips I mention below are all practiced in my house (as much as possible) and I think they've helped Lincoln, my two year old, be able to work his way through tantrums better.
term that sticks in their head as good or bad. Instead, you can say something like, "wow, that was a great decision to help me pick up these toys!"
When you see it, say it! You can't over-compliment your child. You're their main hype-man!
"I'm going to clean the blocks. Do you want to help me with the blocks or pickup the trains?" If' they don't want to get into the car, ask them "do you want to pick our first song in the car or buckle your own belt?" They need to get into the car, but once there, they have an incentive.
Same with certain toys. It's honestly not worth the fight of forgetting it at school or in the car or wherever. It's also good to know something your child can always be redirected to. For us, it's playdough or outside. Always a win.
