I imagine kiln drying of the boards after planing also take away some dimension to a board...? Maybe maybe?
Ivie I have to tell you about that Monogenic Diabetes thing. The friends I shared with it got some Diabetic antibody tests back and they are negative for the antibody. So that is indicative of NOT type 1! They are doing genetic testing next to see if she has the gene mutation that is Monogenic. The little girl had her diagnosis at 7 years old. So it is not always neonatal onset. I wonder about your grandson or step grandson is it...? Has DIL done the testing or asked for it? I know you kind of mentioned it to her and let her take the reins from there.
I think all kids should be tested for this no matter their onset age. It's not always in a Dr.'s wheel house to ask for this testing yet I think. Too new.
