Tips for baby that refuses to latch


I’m 3 weeks postpartum and my babe just will not latch she shakes her head everywhere like she’s looking for the nipple when it’s practically in her mouth. This is my last baby and I really want to breastfeed but I’m not producing anything I’ve been trying to pump but I can’t get more than 1-2 oz when I do supplements aren’t working either I don’t wanna give up but I’m kinda a t a loss at this point it’s been 3 weeks and the longest I’ve gotten her to latch might have been 3 minutes and it’s only on my right boob I tried the shield but it’s way to big for her mouth no mean comments pls tia
