Depend on baby. My baby 1st week taking 90ml and 2nd to 3rd week 120ml. 2nd month 150ml 3rd month 180ml and stuck all the way till 1yo. 2 to 3 hourly.
Is normal :) 2nd month 90ml - 150ml every 1.5 hr to 2 hrly If you breastfeeding, sometimes baby will demand more :)
Yes is normal. Sometimes baby will even want to latch more often not because their hungry. Just for their comfort!
