After re-reading and seeing that he has lows in below 36, and sometimes into the 20's. I have to be honest here, in the 7 plus years we have been at this since my daughter was DX' Ed at 13 months we have only have had a handful of bgs under 40. Most of those while actively sick or on an antibiotic. Somewhere things are really off for you guys, and you have to stop the severe lows. Maybe if you post a days numbers and insulin given we can help you compare and see the "tree in the forest."
