How much does your 6week old baby drink?

Nancy • My daughter Ava Grace is my world! 05.04.16 Expecting March 2019
I breastfeed so it's hard to know how much my baby is getting but when I pump which is often I usually pump 2 1/2-3 oz for her to drink and she usually wakes up every 2-3 hrs when napping. Is this normal? How much does your child drink?
