Low milk

Autumn

I've been pumping but it seams like my amount goes up and down.

One pump it will be 70ml and then go down to 20ml or lower.

Tonight it's only been 15ml.

I've been trying to pump every 3 hours but my little guy is always interfering with it (He is always awake when I need to pump or we have doctors appts)

We are trying to get little one off bottles of formula but I just have a hard time getting pumping in to my schedule and making enough for him to nurse threw a nipple shield.

Is they're anything I can do too bring my supply up?

Please help!
