{{{Hugs}}} That's really frustrating. If it's not normal behavior, when that happens here, I just keep chanting to myself--be patient, this isn't normal, so even though I haven't figured out what it is yet, there's something wrong and I need to love her through this.
Lately I've noticed my kids will do this sort of thing at the onset of a cold--before any symptoms are even appearing. I just try to settle them as independently as possible, avoid any intense AP that will turn a one off into a pattern worth repeating, take shifts with DH if necessary.
