🙏🏻Baby colic/problem with feeding PLEASE IS IMPORTANT

Hi mommies!

Please if you could help me out I am so so stressed as I can find what or where to ask for my baby’s “problem”

I gave birth at 37 weeks as baby wasn’t putting on weight. Baby was born .

Since then I tried everything in my power to breastfeed unsuccessfully but for the first 1,5 months I’ve managed to do it through pumping. Then my pediatrician recommended formula because she wasn’t gaining weight. We changed a few as she is suffering from colic but still she is in so much pain when I feed her! I wonder if there is anything else going on and not just the colic. I am so stressed because she is eating 60ml max we are 3mo today and she takes sooo long to empty the 60 ml bottle:/ please let me know if something similar happened to you and what you did. THANK YOUUUU!!!!!
