Need help for my formula fed newborn!!

Hi mummies with formula fed newborn! May I know how often does your newborn poop and what FM are they drinking? My newborn is 24 days old, initially she poops twice or thrice per day. But now it’s once every 2 days and currently drinking NAN SUPREME HA. I was wondering if I should change FM and any recommendation please 😞 she is crying a lot and farting a lot. My first child was FM as well with NAN HA and I remembered he pooped a lot in a day. But second child seems to have problem with pooping. Hope to get some input from mummies! Thank you!!
