What was your experience like with subsequent births?

I was diagnosed with IGT (insufficient gland tissue) with LO1, which resulted in breastfeeding "failure" (quotes because I was still able to nurse and pump for a year in addition to formula supplementation).

I'm currently 31 weeks pregnant with LO, and noticed today that I leaked colostrum through my bra and shirt. I know that can't be a bad sign, but I wonder if I'm getting my hopes up by being super excited about this!!

My LC told me you typically grow more gland tissue with each pregnancy. Beyond that, I worked hard to get out of my pre-diabetic stage before getting pregnant, and I plan to start some extra supplements at 34 weeks. Any experiences or advice would be super helpful!!
