best thing is do not react to what they say. they are showing emotions but do not know how to express them. talk to them afterwards, well after wards, if necessary but in a melt down they are operating on the emotional part of the brain. talking will not help.no use threatening punishments at this stage as it will just make it worse. physical soothing might help. (big hug, or quiet place alone.) It is ok to intervene physically if they are going to hurt themselves or someone else. (hoiking them back over the right side of the banisters, preventing them running into the road when having a meltdown)
try sunglasses and headphones for her for the car. probably having a change of routine meltdown/mega stress.
make sure hshe eats well. with whatever she will eat. be that cereal or whatever. keep the blood sugar up. make sure she is not too hot or cold or thirsty.
try relaxation activities daily. this reduces overall stress levels.
see if she can attend a mind group on anger. (not that helpful if they can not recognise any of the signals in their body though)
try a big hug.
for god's sake do not laugh, no matter how funny they look in melt down . this is a very bad thing. and can be expensive and hurt a lot. (autistic inappropriate reaction, is not well received by another autistic person in meltdown. oh no)
reduce sensory input.
routine. give time to decompress when she is back. send her to a quiet room with weighted blanket, snacks and whatever it is that calms her.
asd and periods. oh god yes. bloody awful pmt and heavy periods. the emotions are so overwhelming.
feed them. (glucose, sucrose and complex carbs) i imagined sliding the food in on one of those really long paddles used in old fashioned brick bread ovens. ) instead food is placed in front of them without asking what they want or saying anything when it is delivered.then retreat to a safe distance. gets eaten quicker that way and the meltdown passes quicker.
she behaves bad for you as you are her safe space. remember she is probably emotionally two thirds chronological age. definitely behind others.
reduce sensory input and challenges, and things she needs to do before and after going to dad's. be very gentle in preps before you go, giving her lots of space and quiet so that she will be less overwhelmed by the change of routine. do not plan anything for the day before or after. (eg shopping or dentist or visits etc) going places and getting ready to go places send me into meltdown quite easily. children are dispatched to their rooms while I pack. I need lots of sensory breaks.
pda is interesting as that fits the profile of mine. they are definitely autistic.
