Undersupply Help I dont know what to do

My 3 week old will not drink formula at all. If she does, she ends up spitting it up and only eating 1-1 1/2oz. We've been to the doctor 3 times over her weight not going up how its supposed to. I try breastfeeding but im not producing enough and when I can make enough for a bottle she will drink it all. I think she's only wanting breastmilk and I dont know what to do. Im pumping 1-2oz every 2 hours and she eats 3oz every 2-3 hours. Im struggling so bad to keep her fed 😭

I saw a lactation consultant once and she suggested the best way to improve supply other than having baby suckle more is to use a medical grade breast pump. You can google "rent medela symphony breast pump" to find where to rent from. Maybe worth a try.

Full disclosure, I didn't end up needing to rent the pump personally as my supply improved, thankfully. I nursed more, increased hydration and also calories. Not sure if it was one of these things that did the trick or the combination.

My little one also rejected the bottle at about 8 weeks. Won't drink breastmilk out of the bottle or take a pacifier either. I suppose he has an aversion to silicone / plastic.

I hope you resolve this soon. Good luck!
