Hi, My baby is one month on and on formula feeding. How much shd she be drinking? Thank you

In the first few weeks of baby's birth, he or she generally drinks about 60-90 ml per feeding and will probably need to drink every 3 to 4 hours on average. By the end of the first month, baby should be drinking a minimum of 120ml. https://www.healthychildren.org/English/ages-stages/baby/feeding-nutrition/Pages/Amount-and-Schedule-of-Formula-Feedings.aspx
