Full disclosure I've always had a fast metabolism so I don't know if THAT'S why it worked so quickly. But because of my skinny frame, I had trouble producing enough milk, it's something I expected and my doctor warned me about. Looking around for solutions, Boost had an all-natural formula that was safe for my baby, and a ton of positive reviews from across the web including amazon and google shopping. So I bought it a few weeks before I gave birth and I started taking it when Gus was 1-month old. The three-day results were amazing. And I never had to worry about milk again for his entire first year.
I had a lot of trouble producing milk during my first pregnancy, and ultimately we had to use a lot of formula for Brooklyn. My second child was looking like the same, but this time I knew about Boost.
I started taking Boost and less than a week later I was producing enough milk every day, plus more that I was able to pump out and save for later. It was almost unbelievable how well it worked but it was a godsend.
