Breastmilk Storage in my fridge

These are the breastmilk supply I have currently in my home freezer and the freezer in my mum's hse.
Mostly are 4oz but some are 3oz on bad days.

It looks like my storage supply will be insufficient because lately Shern seems to be drinking a lot. He is like a human alarm clock. He cries for milk every 2 hours.

My milk factory max can only produce 4oz every 3 hours.

I think I need to pump every 2 hours now to tell my brain that milk supply is insufficient. Shern wants MORE!
