Screaming at the breast - aha!!!

ami
We weaned off shields and have been shield free for almost a week!
But baby started crying/screaming at the breast - sometimes, but not other times.  I was stumped - thought it was something I ate, or nipple confusion from bottle, or oversupply or under supply... 
Anyway, I finally figured out that going back to the shield solved his distress!  Yay!  just wanted to share in case it saves some trouble for one of you!
