I think I really artificially boosted my supply at the beginning by eating tons of oatmeal. That's the only thing I did to boost my supply and I have WAY too much milk. So for me I'd say yes, that and drinking water boosted my supply me a lot!
I try to eat oatmeal every day if I can. To get my milk to come in I ate lots of oatmeal, turkey, brown rice, and sweet potatoes. Then I had oversupply issues. I stopped eating oatmeal for a little while and my supply dropped, so I'm back to eating oatmeal almost every morning and pumping to keep up with my supply again. So I put my faith in oatmeal for sure!
