I read a bit about diabetes and pregnancy before I had my first daughter, but do not remember seeing ANYTHING about breastfeeding and the impact on the woman with type 1. Let me tell you, there is an impact. A big one. Hoping we can document what happened to our bodies for all those new or soon-to-be new moms out there with type 1 who want to breastfeed.
You get that precious little baby and are ready to nurse. It's a great bonding time, healthy for baby and a great way to get weight off. But it also takes a lot of energy out of you. I have heard horror stories of type 1 moms losing conciousness while breastfeeding it drops blood glucose so fast.
It took me a while to get it nailed down, but this is what I found worked for me. I would start by doing a BG check and hoping I was in good range (cause baby is crying and being low is not good). Assuming I was in good range (above 100), I would get 6oz of orange juice in one glass and 6oz of orange juice in another glass. I would drink the 1st glass before starting. Feed one side. Drink the other glass, and then feed the other side. It took me at least a week to figure this out. (Remember - you are feeding the child every 2 to 3 hours at first... this is tough stuff to figure out, especially when you've never nursed a child before and have to figure that out). So, figure that's around 60 grams of carbs in one nursing session, doing that 8 to 10 times per day... a HUGE amount of carbs going in and you still lose weight.
One other thing, it would be a really good idea to have someone with you for the first week or so after you give birth to help support you and the baby while you get your blood glucose all figured out. Thankfully, my husband was able to take two weeks off after the birht of both our daughters.... just like diabetes adds a bit more onto other areas of life, having a newborn is just a little bit more work and having extra hands is very helpful. So if baby's dad can't be there, see if your mom or a friend can take turns coming over. It can be a very difficult time to be type 1 and you could get yourself into a scary spot alone with a newborn and being low. Best to have some help.
