I feel that my boobs have unbalance milk. I tried to express out from both sides but my left side yield more than my right. Is that normal?

Im the other way, my right side yields much more than my left. Right now i counter by pumping the left slightly longer

Yes, its normal to produce different quantities each side. In fact, my supply only balanced out around 1 year pp!

Very normal. One side will always yield more. Sometimes it can be even 2 times more than the other side.

yes it's very normal! Our boobs milk are always imbalance. One side will def produce more then another

Yes normal. Even our boob size is different. Just like our feet

Normal dear. One side will always yield more. Don't worry

Yes it’s normal. I noticed the same with mine too :)
