Haaka pump, hind/for milk 🤷‍♀️

Amanda • 💕💙 Blessed mama to a Beautiful Boy and expecting another💙💕

So when I nurse I normally have baby on one side and the haaka pump on the other boob and switch boobs for each nursing session. And I get like a good 1 to 2 oz each time. I do this cause I’m usually too lazy to pump and/or forgetful. But more importantly I keep hearing about hind and for milk. Is this something I should be worried about? So far I’ve just been bagging whatever i get from the haaka for my stash. Any info and/or advice would be helpful, Thanks in advance.
