Baby with blood sugar trouble

Hello I'm wondering if there's anyone else out there that has a baby with blood sugar trouble. My daughter was born a month and 2 weeks early at 2lbs ad 2ozs because of preeclampsia and being growth restricted. A month before she came home her sugar started trouble. Now that she's home shes on meds and has 3 sugar checkes. How do you cope? Some days its hard, because I'm always wondering what if I did something. What could I do better. Shes now 4 months old, 2 months adjusted
