I need all the advice and tips I can get PLEASE 😩😢

When my son was first born I was told I couldn’t breastfeed so we started bottle feeding and I wasn’t keeping up with pumping....then days later I was told I actually should’ve been breast feeding and now my supply is low! I get about an ounce A DAY!!! 💔

Is there anything I can take, drink, or eat to get more milk? I’ve already tried a herbal tea sold at Walmart for milk supply but that hasn’t helped.

Also, do breast pumps make a difference? I feel like the one I have isn’t sucking hard enough, maybe it’s the brand?

I have met with a lactation consultant and didn’t learn anything so I’m basically on my own here 😔
