Actually, the sock issue has gotten better. I still look for socks that I know are more comfortable for him. It is just one less physical irritation that adds to his overall irritability.

He used to also not want to put his hands in mud, sand or touch clay. The OT worked with him on that issue by taking a backing dish filled with dry beans and then burying hard candy. My son had to "dig" with his fingers to get the candy. Sometimes the dish held sand. He now doesn't mind getting his hands dirty... and I sometimes can't believe I'm saying this, but we were all so thrilled when he walked around with dirty hands !! OT also helped him integrate sensory issues that made hair washing a nighmare. He now washes his own hair just fine.

For us, the hardest part was learning to pick your battles and to let lots of things go for another day as you worked on one or two issues at a time. And so I didn't make a big deal out of hair washing at every bath time - but we did a big celebration when he allowed his hair to be washed without a fuss. We went for ice cream. My son was so pleased with himself !

His pickyness about getting his hands in stuff impacted his school day in that KG does lots of art and play. And so the teachers would report that he was refusing to cooperate.. blah blah. And not only would he refuse to participate, he would explode.

I know what you mean about one minute your grandson being an angel and then the next... look out !! Over time you will learn what the triggers are and then the explosions won't seem so "out of the blue". And once you identify the triggers, then you can work on managing them to reduce the number and severity of blowups. Then you pick a few and work on integrating them. Some issues, like socks, may never integrate - but at least hopefully those triggers will not produce such an extreme reaction.

Your grandson is already ahead of the game since the school is helping out with the interventions. That is so great.

Hope your trip is save,
