Hi, I’m new here and need someone’s help, my son was diagnosed with ASD over a year and half ago, he is 4 years old but over the past 7 months he started having really bad meltdowns to the point where he hits himself, he is nonverbal but leads by hand. When he has his meltdown it can last as long as 2-3 hours, in that time I try everything and anything to help redirect his attention, by putting on his favourite tv show, putting on sensory lights, giving him his favourite toy you name It I try it but once he starts his meltdown I can’t seem to stop it. Does anyone else have this and if so how do you help calm your child? Please help I would really appreciate it, it just breaks my heart to see him like this.
