You can give upto 90 depending upon weight of baby (if more than 4kg )but many times baby want to suck —— so the breast feeding is the answer as there is no scope of over feeding

Mother milk is so important for baby's growth and development Try to serve breast feed  only If inadequate then try some medicine to increase milk if still inadequate Then only can start top feed ie  powder milk Feed ur baby as per his demand No matter the quantity Sometime he will take 120 ml or 30 ml baby should sleep comfortably atleast  2hrs after that.  And should pass urine minimum 6-8 times per day Thats all
