Can I regulate my breastfeeding?

Heather

I feel like I don’t produce quite enough to feed my son ALL breastmilk so I have been supplementing with formula and that works fine. I would love fine giving him mostly formula during the day and breastfeeding for bed and anytime he wakes up in the night and early morning. Is there a way to train my body for that or is it even possible? How do you do it if so?
