I also have a family history of diabetes so I completely understand the worry, and the Freestyle Libre is worth asking your specialist about because it is a continuous glucose monitor that scans instead of pricking, which many mums with GDM find much easier to manage day to day. That said, your specialist or the KKH diabetes team will be the best person to advise whether it is suitable for GDM monitoring specifically, since some clinics have their own protocols on what devices they accept for tracking. It might be good to bring it up at your first specialist appointment and ask directly, so you can weigh up the cost and whether it fits what they need from your readings.
