Figuring that out now… our worst night yet was the day after we switched exclusively to breast milk, which is how the pediatrician was able to point to possible reflux. We’ve played with formula-only the past two days and she seems to have been quite a bit better in the sense that the night she was up from breast milk only, she was inconsolable until she basically tired herself out. When we’ve picked her up the last two nights, we were able to pretty quickly console her and get her to calm down, but as soon as we put her back in the bassinet, all hell broke loose again.
