How to tell if newborn carried out with diabetes?

Ka

I had gestational diabetes and when baby was born they checked her levels for 24 hours and she was fine all normal results but I have noticed her nappies are always full of pee like I mean really full in the space of an hour or two. She is formula fed has 120mls every three hours. It says frequent urination is a symptom of diabetes could it just be from all the formula she has?
