ADHD medication and breastfeeding

I got the green light to start vyvanse again (for my adhd) on a very low dose 20mg. My normal is 40mg but plan to stay low just in case… So the green light was from my ped and ob/gyn… however, my primary dr was hesitant and it has me feeling uneasy about starting the medication. I’ve read the research but I’d like to hear personal experiences from those that opted to start adhd medication again.

How did it go? Baby show side effects? Did it hurt your supply?
