Help, please!!

my baby’s 5days old. she’s very good at latching but she won’t take the boob 😓 my nipples aren’t as poked out as she would like. i was using nipple shields but it seems as if she doesn’t like those either. so i’ve been trying to pump as much as i can because she eats every 3hrs. but i’ve been studying myself and i can only do 4.5 colostrum bottles within a 25min time frame. after about 25mins nothing comes out.

what do i need to do? i don’t want to transfer to formula, i really want to breastfeed and pump but this is becoming so depressing 😢
