My son is five years old...diagnosed 11/30/11. At diagnosis, he was put on 1/2 unit of Humalog per 12 carbs and 1 unit of Lantus in the pm. He was having way too many lows during the day and night so he was taken off Lantus all together and his Humalog ratio is now 1/2 unit per 18 carbs. Things were steady for a quite a while. Moving along....his number during the day and night had been rising. Sometimes, he'd go to bed at 150 and end up around 200 to 220 at his 2 am checks and upon rising. Also, I couldn't seem to fight the higher numbers during the day 200-300 all of the time. So, his endo gave me the option of trying the Lantus again (she knows it makes me nervous). We are now giving him 1/2 unit of Lantus at 8:00 p.m. It does keep him around 85-100 all during the night (which makes me a bit nervous since it is closer to that 70 mark than I am used to now) but all was well and his numbers during the day are usually between 80 and 200. Today, was his birthday party (piece of cake, hotdog, etc.) we bolused accordingly at about 12:30 and at 2 hours after he was at 303 (which I expected because he's always high after cake, pizza, etc. because I don't yet trust myself to bolus more than usual for those pesky foods at the risk of going low) and at 3 hours later (with no more insulin) he was at 220 (which to me seemed good). Then before dinner at 5:00ish, out of nowhere...bam...he had tanked to 55. I'm thinking that the 55 is an indication that the Lantus was still in full swing 22 hours later. So, it makes me a bit nervous giving him Lantus again tonight due to possibly stacking the Lantus. Is that possible, or is it more likely that the cake, etc. made him high and then caused him to crash? As always...thank you!
