GD with first child but not others?

Ni

I was diagnosed with GD early with my daughter and my numbers got progressively harder to manage in that pregnancy and I ended up going on insulin. But I’m now 15w6d with a boy and so far my numbers have been pretty good and my doctor hasn’t diagnosed me with GD yet. But I’ve been checking my numbers randomly just in case. I ate waffles with syrup, toast, and OJ last night for dinner and my glucose number was only 115. I’m shocked!! I know I still have a long way to go in this pregnancy, but anyone have GD in one pregnancy and not have it again??
