Night feeding


I’m my lo is 1 month - she ofc still wakes up in the night twice which is fine I don’t mind but she doesn’t eat like she does in the day, she’ll eat prob 8-10 mins then pass back out and be good for the next 3-4 hours. Today I woke up with a sore boob, she’s already ate her regular feedings 15-17 mins this morning but it still hurts I’m not sure if I should pump it or not. Bc I don’t want it to take away from her food next. It’s not rock hard or anything it’s actually flat but it it still hurts
