Congrats sa pregnancy, mama! Since you have GDM, honestly best to check with your OB muna on which milk supplements are safe for you, may mga brands na mas okay para sa gestational diabetes kaya importante na doctor-approved ang choice mo. You can start anytime really, pero maraming moms dito start around 7-8 months para ma-prepare ang body for breastfeeding, and your OB can give you specific reco based sa blood sugar levels mo. Wishing you all the best sa remaining weeks!
