Newborn less than 1 week

Hi mommies, I just gave birth via c-sect few days ago & had tried breastfeeding even though I not sure is there any milk. But baby did managed to pee & poop like 1-2 times in the ward, & doctor said its normal. So now I'm at home, did breast pump then realised I have no milk. So no choice I switched to milk formula while waiting my nipples to heal from cracked. But I noticed my baby usually sleeping & doesn't wake for feed. So always I have to wake him. For now he drinks abt 30mls of milk every 2 hrs but still doesn't poop frequently. Like today, only poop in morning & wet diaper (not heavy) like 3 times. KK nurse ask me to increase feeds which I did, but pee/poop part worries me. Any mommies also same issues? Worried & stressed #AskingAsAMom #Needadvice #firsttimemom
