Do remember that in the first 2 or 3 days, milk produced is yellowish and less and in fact known as colostrum
which is very important for your baby's health and overall immunity. So even though it was less I hope you would have given it anyway. Milk production gradually increases over time and as a mother you should always nurse your baby with breast feeds as it is the complete "food" for the baby till the first six months of age. If you are unsure of the exact quantity, you can always express milk in a calibrated glass and check every 2 hours. If the quantity of milk is anywhere between 25 to 30 ml or more, it is adequate for your baby. If you are a working mother, you can express milk and store in refrigerator for upto 24 hours. A good urine output does not always indicate that breast milk is adequate as it could just be foremilk. So most probably the milk production is not adequate as the baby cries after feeds. There could be other reasons for his crying as well but you need to ascertain adequate milk production first before drawing any conclusion. You need to nurse your baby every 2 hours and your baby should get sound sound sleep for approximately 2 hours in between feeds.
Hope that answers your queries. Why I have deliberately not commented on bottle feeds is because I wish to motivate you on breast feeding your baby.
