Unsuccessful Success

Brian was sleeping and I decided to try and tandem breastfeed.  It was good at first because both girls latched and fed for a good 20 minutes or so.  Fast forward 5 minutes.  I put both girls in their swings and they were happy for like 5 minutes.. then WAAAAAAAA. They were both still hungry and not happy.  Grrrr. Now to try and feed them with bottles at the same time.
