First this is easier said than done!!! We were told to check physical needs first. Is that *scared* cold, hungry, thirsty, tired, lonely, etc. Not to ask what's wrong initially. Then what else can do...shower, listen to music, coloring book, go
for walk, eat healthy food, sing. Then later when things quiet down ask what happened. My reaction has always been to want to find out what's wrong & fix it. But have found out M&Ms can be magic!
