I’m pretty sure the missed doses won’t matter, but if it were my kid, I’d call the endo to be sure.

We’re like most of the other people who have posted - usually we’re "like clockwork", but there have been very occasional slipups.

I’d be as concerned as you are about this. I think it’s a fairly significant issue. If it were me I’d work with my kid - not against them - so that they "get it" about how important the meds are. I guess how you do that depends on your family. But I’d be fairly upset if I found out that this had gone on.
