Ok so my son is getting over a fairly bad cold, but the past 3 mornings he has been getting lower and lower. First it was 83, then 68, this morning 39!!!!!!! I have no clue why its doing this!!! He has 1 unit of lantus before bed, and it has been like that for over a month now and he usually wakes up in the 130's. He has already gone through the MAIN part of his honeymoon period. His doctor said he was still honeymooning, but now needing the insulin again. What should we do!? Could it just be from the cold and the excitement of Christmas/being at grandparents??!
