so I've been pumping for 3 days and my Breast hurt if I don't pump so much but my baby girl don't…

Pumping keeps the milk flowing. If you have an oversupply, continuous pumping makes it worse. Thats why most lc dont recommend pumping until after 6 weeks when your supply is regulated unless you are strictly pumping and not putting the baby to your breast

pump and store it in the freezer

You'll have more than you need in the beginning. It'll regulate in some weeks.

And how often do you pump?

, but don't stop pumping all together or you'll get plugged ducts which may lead to mastitis. Slowly cut down the number. Slowly!

Try to massage your breast while you pump to help get the milk out. If your nipples hurt you can try coconut oil to lube while you pump or BeauGen's nipple cushions. Also make sure you pump often enough so you don't get any clogged ducts. You're doing a great job mama!!

Thank you! really feel like I'm not doing good enough so thank you really makes me feel better @tulegit2quit
