Witching Hour?

Lauren • Baby boy Nate born 10-07-17

For the past 3 nights my son has been inconsolably crying from 10pm-1am. He screams his head off and nothing works. Nursing him helps a little bit, but I have low milk supply so he's not really getting anything from me. We have a pediatrician appointment this afternoon, but does anyone have tips on how to deal with this? He's 9 days old.
