Hey mama, I totally get the worry, a few of us went through the same thing! Honestly, the best thing I did was make sure to breastfeed frequently (kahit parang wala pa talaga), stay hydrated like crazy, and eat protein-rich foods kasi that really helped my milk supply pick up. You can also try pumping after feeds para ma-stimulate ang production mo pa lalo, and one of my mum friends swears na nakita niya ang difference when she started taking malunggay or oatmeal regularly.
