Baby suddenly ravenously hungry!

Hey all,

My baby is 5 months old. He is mostly breastfed, but I have always been an undersupplier and struggle to keep up. Last month, my baby was regularly eating 3 oz and so he was purely breastfed.

Then out of nowhere, overnight, he just jumped to like 6-7 ounces and my body couldn’t keep up with the rapid change!

Now I have to supplement the rest with pumped milk.

Anyway, I guess I just wanted to ask if anyone else saw a sudden rapid increase in ounce intake between 4-6 months?
