What’s the main risk of taking vyvanse while breastfeeding? Have any of you taken it?

There just isn’t enough research on it at the moment to make a determination on whether it’s safe or not. I stopped taking my ADHD medication (35 weeks now) by weaning myself off. It’s been tough without it, but personally didn’t want to take any chances. However, I’m a firm believer that if the reward for your functioning/well being outweighs the risk that may not exist, you do you, mama!
