My 11 year old son was diagnosed with type 1 diabetes in November last year and is coping really well. However last night he was particularly high at 18.5 machine was stating to give bolus of 1.5 units he didn't want to have this and was concerned about going low through the night so I went with his gut instinct and sure enough this morning he woke on 4.1. My concern is if we had followed his machines advice he surely would have been dangerously low??
