Not enough

Dakota

I’m scared I’m not making enough milk for my baby he’s 5 weeks and ever since he was born I’ve been breastfeeding and supplementing formula but the older he’s getting the more he eats and it’s mainly formula. I want to ween off the formula but when I pump I’m only producing around 2 oz that’s if I’m lucky and I know that’s not enough for him. What do I do to produce more milk
