Is it normal for a diabetic to have a hypoglycemia episode every day?

My grandma recently began taking insulin shots for diabetes. Every day between breakfast and lunch, however, she's been having a hypoglycemia episode with shakiness, sweating, and weakness. This doesn't seem right. Today she even had 2 breakfasts, but still had an attack at lunchtime. She is the first one in our family to have diabetes and be on insulin, so we're all new at this. Is this normal?
Thank you so, so much for your answers!!!
