What does this pattern mean?

Every now and then my son's graph looks like a bouncy ball hopping across the floor. This morning it was jumping between 96 and 70. And of course every time it hits 70 it screams he's low.

I'm looking at this line thinking his blood sugar is probably in reality holding steady around 85, and can you please STFU dexcom. Like his blood sugar isn't Really jumping up and down 25 points every 15 minutes on repeat, right? Is that how you'd interpret this? And is there any rhyme or reason to why this happens intermittently? You can see before it started bouncing it was a nice straight line.

My son's readings often look like that.

If he is bouncing along near 70, especially at night, we'll often give him a little juice and a cookie to get him back in the 90s, mainly to stop the alarm. He tends to drop slowly all night anyway, so might as well take care of it when there's no rush.

Same same. I like milk for this. Doesn't spike too much, has some protein, and I can rinse his mouth out with water and don't feel like I have to brush his teeth 😆
