Baby poops while eating!

Ugh! Happens at least 2-3 times a day and it drives me crazy because she won't eat anymore after, even if I change her right away and I feel like she wasn't done eating. She doesn't seem upset or anything. Sometimes she only eats for like 3-5 minutes now, too. Hoping it just means she's just more efficient at getting the milk she needs. Anyone else's baby poop while eating???
