How to increase supply at 8 month postpartum?

Hi ladies! I was producing 40 ounces a day. I was pumping ever 3 hours. Then my LO went over 3 month eating strike where he would only eat 30 ounces so I started weaning of pump and pumped every 7 hours. Currently I barely produce 30.

Well now he has decided to start eating again 35 ounces a day.

I went back to pumping every 2 hours. I was doing that for 2 weeks already but my milk instead of increasing keeps going down. Having formula shortage this stresses me out.

Any advice? Any successful stories or reestablishing your supply? I need inspiration, hope and motivation to keep pumping every 2 hours.
