Is there anything we can do to get our milk supply to come in quicker? Worried about not having any during the first few days.....

You can consider pumping and using the lactation massager. Can help to improve milk flow. And if you’re like me who had blocked ducts from the beginning, the lactation massager is gonna come in very handy also. Better than massaging on our own, it can really get a bit tiring after awhile. https://welovesupermom.com/products/lacmas-r-lavie-lactation-massager-available-in-2-designs
