Kak, I understand la this is scary first time, especially dengan GDM on insulin, but honestly, whether baby needs NICU depends on so many things like baby's blood sugar levels right after birth, breathing, and how stable baby is, so best you discuss this specifically dengan your OB/GYN and the hospital team sebab they know your full situation. Biasanya babies of GDM moms do get closer monitoring after delivery, and some hospitals ada protocol untuk check baby's glucose regularly dalam first few hours or days, but tak semua kena NICU stay, many are okay with close observation aja; your doctors will explain the exact plan before you deliver so you're not caught off guard. Jangan stress too much, you're already managing well dengan insulin, and the fact you're preparing shows you're doing great. Take care of yourself, okay?
