She's been waking up every half hour for four nights straight, crying and pooping. She only calms down if I hold her or if she's on my chest. Then she wakes up at 4 or 5 AM (today at 3:40), and hangs out for another hour and a half. ? To say I'm "not in the resource" is nothing. For a whole week before that, we were struggling with diaper rash, now these nighttime wake-ups. People, where do you get the strength from?
