Symptom narrative

behavioral changes: no longer looking to self-soothe, stopped rolling over, stopped thumb sucking, VERY disrupted sleep, couldn't be put down (previously very independent sleeper), incosolable, blank stare/expressionless (previously very smiley baby). These changes happened that same day of vaccination and lasted weeks. she began behaving "normal" again after about a month. We separated the next round of vaccinations at 6 months and she had a similar experience but in addition to all that developed FPIES to avocado - a previously tolerated food.
