Type 1 diabetic mother breastfeeding.

So, With my first baby I didnt produce anything for him and he had to go on formula. This pregnancy Im hoping to be able to breastfeed 🤞🏼my sugars are very hard to regulate so Im afraid that it will ruin my breastmilk for her? If that makes sense.. or be too sugary and unhealthy? Idk.. Im unsure about anything to do with breastmilk and any tips from a type 1 insulin independent would be AWESOME!
