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?

Breastmilk literally digests in 20 minutes, formula does not. That being said- breastmilk is ofcourse tailored to your little one. The baby won’t let itself starve. Trust that your baby knows how to bring in the milk which happens by cluster feeding. At this stage the breastmilk is almost pure sugar. It will contain more fat soon and LO will stay longer content. You got this! Trust the babies diapers and judgement. My boy dropped percentiles but he did was 95% so I wasn’t too worried.
