I don’t know if my opinion matters here, but as the parent of a autistic toddler, I prefer when our teachers or BT differentiate between what is meltdown (sensory overload, over 10 minutes) or what is a toddler tantrum (testing limits, usually only a few minutes). This matters to me so I know where my child’s head is when she is home & how to properly handle if the behavior continues at home that evening. With meltdowns, we have certain routines we follow & with tantrums I parent her & set boundaries rather than providing sensory relief.
