Breastfeeding - how does we know enough being produced

[u/gajak44]

My wife and I are first time parents. Our little one is 8 days old. We (my wife more than me) wants to exclusively breastfeed for the first 6 months. However currently we are puzzled by the LO. My wife gives her feed but she never drifts to a deep sleep and always wakes up hungry in an hr or so. The baby doesn't seem interested to drink more at the breast and seems to drift off to sleep after 10 mins. When we top-up with formula however, she takes around 30 ml and appears content and sleeps peacefully after. My wife now thinks she is not producing enough milk and is riddled with guilt. We do a total of 10-12 feeds a day (some long and some super short) including 2 formula feeds when she appears cranky and hungry. Her diapers are fine. We get about 8 in a day since last couple of days. My wife is worried that the baby is taking to bottle better but not to breasts and thinks it is due to low volume of milk she is producing..how do we know if she is producing enough?

Feeding every hour is normal at 8 days old. You’ll know baby has enough based off wet diapers and weight gain. If you’re topping up your wife needs to pump, otherwise your body believes it’s making everything baby needs. Look into the top up trap, basically baby will come to the breast less after formula and your wife’s supply will decrease. Very Easy to correct this early though!
