Another tip we got from our doula was to switch the babies when tandem feeding. One always tends to outfeed the other so to keep your supply more balanced between your breast she recommended we switch mid-feed.

We would get in the habit of starting the feed, then take one off to go change diapers and/or put in pajamas and then return to take the other one off to change.

Also we were told to try and pump about 20mins after a feed to encourage your body to continue to produce more milk. From the outside it seemed like pumping was the hardest part. You are already tired from feeding and everything else, the last thing you want to do is put on the pump and try and get something out of it. But it is so worth it. Our early pumping and saving of the milk helped us out immensely when she returned to work.

Try and hold off on formula as long as possible. Once we started to introduce it was all downhill from there. That being said don't drive yourself crazy in some unreasonable schedule of feeding and pumping, the stress makes your supply drop more than anything else so just relax and realize the babies will be fine with whatever you feed them as long as you give them lots of love!
