My health visitor told me an EBF baby won't poo every day as breastmilk is highly digestible, so baby will absorb almost all of the nutrients and there will be no waste to poop out. My baby would go upto 6 days without pooping sometimes. I think they only worry if babe is under 6 weeks and hasn't pooped for 3 days x
I ebf 3 babies. They all had different pooing habits. The first pooped multiple times day, lots of little poops, she was also the most colicky and snacks feeder. The twins pooped every couple of days and they were like change your outfit size. All gained weight and overall normal amount of small baby content so I wasn't worried x
If weight gain is good then try not to overthink it tbh! There's a 'standard' amount because that's what most do, but it doesn't mean that all of them should, I'm assuming because breast milk is thinner than formula it gets processed through more quickly. Maybe your milk is just a bit thicker or something! There's no real non invasive way to find out for sure but if there was a major bowel issue or something it would likely become clear very quickly and baby wouldn't be thriving.
