Great advice I read in a book called
I Can Problem Solve (get this book it has magic inside) was in getting little kids (really little, toddler to kindergarten) to stop interrupting. By asking them a question that makes them understand, they gain the perspective required for patience.
Mom: on phone yakyakyak
Kid: Mommy! Mommy! Mommy!
Mom: Dear kid, can I listen to you and isten to the phone at the SAME TIME?
Kid: No.
Mom: Then can you do something DIFFERENT while I am on the phone?
Kid: got it. Different. Mom can’t do that at the Same time.
And they go away understanding you are limited. It was amazing. And then you get back with them later.
I really liked that book (and no doubt the website has lots of good too) as it gave specific dialogues that got into the heads of HOW kids think and provided what they craved (information) in a language they understood.
