Low milk supply

Long post alert

A little back story. My son is 5 months old and ebf. I usually have about 5 bottles of breastmilk in my fridge at a time. He gets about 2 bottles a day and is breastfed the rest of the time. I pump in between feeds and usually swap the bottles out that way. However, this week has been crazy. I booked a gig, had an appointment and my mother and MIL have been watching my baby. I haven’t had time to eat, pump or nurse and I got really lumpy boobs both days. This only went on for two days (Monday and Tuesday) but by Tuesday night my son seemed very hungry. I kept nursing him, pumped the next morning before his feed and I only got 1.75 ounces and thats from both breasts.

I kept pumping before his feeds and sometimes I would only get .75 to 2 oz. He refused formula yesterday, but finally took 2 oz of formula today.

His diapers were not filling up the way they usually do. He had 1 heavy diaper in the morning, 4 lightly wet diapers and 1 barely anything there diaper.

Im thinking bc i let my breasts get clogged and lumpy I have killed my supply. I also haven’t been eating and drinking enough. Stress can get added to that list. It’s been two days of eating, drinking, pumping, and nursing like crazy with very little improvement. Is it possible I have killed my supply for good? Has this happened to anyone? How long before my supply comes back? My LO is barely taking formula ...

UPDATE #1

I’ve drunk almost a 1/4 of a gallon of oat milk. Woke up to pump and got 3.5 oz

I’m hoping my supply continues to increase. 🤞

Update #2

I have pumped 4 oz this morning, and that’s after all of his nightly feeds.

I’m cautiously excited.
