This has happened ever since 3 months old, she's 10 months old now. Sometimes my baby gets into big fits of anger that make her completely zone the world out and she's just screaming and thrashing in anger. The best way I can describe it is similar to the disengagement of a panic attack, where nothing can comfort her or bring her out of her screaming fit. This mainly occurs when she's being put to bed or if she wakes up and is inconsolable in the middle of the night.
This does not seem to be tied to any type of pain. When this happens she's inconsolable and won't respond to cuddling, walking around, shushing, rocking, or any type of soothing. She acts like she's completely in her own world of anger, the only thing that will work to soothe her is giving her a pacifier.
