Formula Feeding Mommy

I know most mommies here are BF mommies but I am one of those mommies na hindi binigyan ng enough supply to feed my baby. Though for the first week I had milk and it's good kasi nakuha ni baby ang first milk ko but my supply didn't met the demand. I would like to ask who are those mom na formula fed ang baby nila? Can you share some tips about FF? I'm a first time mom and sometimes I overthink kasi ang dami ko nakikitang stories about FF like halak, sa baga daw pupunta if not fed right.. just some tips/reminders will be a big help and appreciated. Salamat po. :-)
