Building a stash with cluster feeder

Hello,

Ftm here.

I have a 2 week old that has been BF since day 1. This week has been hell and after a conversation with dad, I decided I would rather pump and bottle feed ( please no negative comments)

I'm having a hard time BF and being able to pump and store milk due to cluster feeding...literally she wants to nurse every hour on the hour.

Any suggestions, tips or tricks

I've been able to pump 2-3 oz here and there but then I turn around and feed that to her at her next feeding.

Should I just store what I do pump?
