Aww, that's sweet na gusto ng baby mo mag-breastfeed! Honestly, a few of us tried Natalac din and nakita namin improvement sa supply, pero depende talaga sa bawat mama, some of my friends swear by it, iba naman parang placebo lang para sa kanila, hehe. The good news is na ang frequent feeding (which baby mo is doing now by refusing the bottle!) is actually the best way to boost supply pa, so that's already helping you. I'd suggest checking with your OB or pedia pa rin para sure na okay ang Natalac for your breastfeeding journey, and they might have other suggestions din based sa baby's needs. Rooting for you!
