How are you handling the explanation of the testing, meds/injections, dietary restrictions with your older LO's? 
DD1 was still just a baby when I got pregnant with DD2 and was oblivious to all the GD stuff. This time she is 3.5 and incredibly curious about everything. She's already asking why I can't eat certain things, why I'm poking my finger, etc. I haven't done an insulin injection in front of her yet, but if they add it at meals as I expect they will I may not always be able to avoid it. So far I've just told her these things are helping keep me and our new baby healthy, but the questions are getting more in depth and I'm not sure how best to explain it all to her. Thoughts?
                 
                
Re: GD/Diabetic moms with older LOs
I've explained about the "juice" the pancreas gives out and how mine doesn't work right but I"m sure it's over their heads.
Now with my pump (she saw the infusion site the other day when I was in the bathroom and got distressed again), she knows it is the new ins. She will come over and point out the different parts of it. I've explained that this is mommy's medicine and it keeps her healthy. She says "yah" and shakes her head and goes on her way.
I can't quite comprehend how much a 3 year old will understand, but just answer honestly. Obviously you don't have to be scientific, but you can probably tell her that it is a medicine to help your body parts remember what to do since many things change during pregnancy.
