Poopy diapers

How many times does your little one poop in a day? And how can you tell if there’s mucus in breastfed poop? My almost 6 week old poops almost every hour, and it’s ALOT each time, almost blowing out. I exclusively pump so she gets boobie in a bottle. TMI but her poops are just like a thin bright yellow liquid, no thickness to it at all. Just wondering if this is normal
