Moral of the story: My experience has taught my regardless of crying at home: keep nails short as Stressful Shit can happen with nails when out in public.
Soaking the hands in the water of the bath softens the nails up so they are not hard to the cut of the scissors. Hates his nails being cut! He dreads it and Dad and I dread it because he perceives the cutting of the nails as painful! It’s agony for him. But, I as a Neurotypical do not understand I know it is painful for him. It would be great to leave them but we can’t as we have found out from experience that he can scratch himself or the nails will grow too long, get brittle and snap off!!! Oh for goodness sakes!
Once when we were putting on his wetsuit to go in the ocean at Port Elliot, we were getting ready for a surf-lifesaving class. While putting the tight suit on, his nail of the big toe totally snapped off exposing the fleshy underbite. It Bled! This was all too much. It was painful! The associated screaming and crying went on for longer than you could have reasonably thought possible. We only had a day tent for him to curl up into.
Eventually he did join his group much to encouragement of his Mum. In order to join the group he had to do some walking. He would not walk on the sand. He’d had to take the most difficult of paths to get there and I was worried he might injure his foot again. I did not want him to embark on the loud exposee’ again. Regardless of what I think, he has worked out that raising his voice and screaming demands at Mum is going to get him what he wants.
He was encouraged to put his damaged toenail in the water to help it heal and this of-course pre-empted another explosion of loudness (screaming and crying) from my dear son. Oh, this is so boringly normal to us! As I had been commanded to go back to campo and get his shoes or something, I was not there when it happened and came back to find a sobbing little boy on a rock! I know that sea water would help but to my son (with broken toe nail!) it was devastating and a bad day!
