Today I bought a pump and started pumping for my 4 week old daughter mainly to make outings more easy (I mainly Exclusively Breastfeed). However, I pumped for 20 minutes and maybe got only an ounce and a half. I was wondering if this is normal or not. It makes me wonder if my little girl is getting enough to eat from my EBF. She seems satisfied after a feeding and she has normal poops and pees but she isn't due for another well check-up until the 30th and I won't be put at ease until I see that her weight is going up.
