Pregnancy usually catches a couple off guard. It's normal to feel a little freaked out and overwhelmed. But that doesn't mean you won't adjust to the idea and be good parents.
There's no reason your fiance can't have a successful pregnancy and that your baby won't be perfectly healthy. Every diabetic mom has a few high and low blood sugars. Don't stress about what happened before your fiance knew she was pregnant. She should just do her best to be in good control from this point forward.
No pregnancy is easy or trouble free. I stressed my child would be hurt by my diabetes or become diabetic; my husband stressed our child would get the heart disease prevalent on his side of the family or turn out like his weird uncle who never had a job. =) Diabetes does bring challenges to a pregnancy, but thanks to insulin pumps and modern insulins it's unlikely your fiance or child will have diabetes related problems. If you do, you will deal with them just like any other mom and dad.
With a pump your fiance should be able to get into tight control. A couple things I'd recommend:
- Get Cheryl Alkon's book "Balancing Pregnancy with Pre-Existing Diabetes: Healthy Mom, Healthy Baby".
- Sign up for weekly updates on babycenter.com or similar websites.
- Work with your doctor to set a lower, but safe target blood sugar.
- Test frequently or use a CGM to quickly catch a dropping blood sugar or correct a high.
- Get a carb counting book or app and carb count carefully.
- After the tiredness of the first trimester wears off, consider doing a mom's workout class offered through many hospitals.
- Work with an OBGYN that you really like.
- No that no matter how tightly controlled your diabetes is, a diabetic pregnancy is considered high risk. You will have more doctor appointments and ultrasounds than a non-diabetic mom and may be encouraged to induce early.
I was diagnosed with diabetes at age 4 and never planned to have a child because I thought it would be too risky. Thankfully God knew better and I became pregnant unexpectedly after having diabetes for 28 years. My A1c was around 7, but once I learned I was pregnant I aimed for a non-diabetic A1c and had a target blood sugar of 80 with no lows. My A1c quickly dropped to a 5.1. My pregnancy was healthy and I had no complications during the pregnancy or since. I had a great male OBGYN and though I was his first type 1 mom, he was quick to get advice from colleagues and he trusted me to manage my diabetes. I also had a great moms-in-motion yoga and water aerobics classes that helped me feel good and meet other expectant moms. My son was born at a normal weight with a normal blood sugar. He's 6 now and is perfectly healthy.
I was extremely worried about passing diabetes to my child and was glad to learn from the American Diabetes Association that Type 1 does not have a strong genetic link. "If you are a woman with type 1 diabetes and your child was born after you turned 25, your child's risk is 1 in 100. Your child's risk is doubled if you developed diabetes before age 11."
I wish you and your fiance the very best and hope you'll keep us updated.
