What is enough?

How do I know if I have "enough" milk?

My baby was born 7lbs 11oz and at 4+ months is 17lbz 10oz so I definitely have had enough milk for the past 4 months. She is EBF and has never taken a bottle. I've always let her comfort nurse and I feed on demand.

I always see people say they don't have enough milk but my baby doesn't even switch sides during a feed.

Will I notice if I stop making enough?

I'm so confused.
