My LO had second flu and third hep B shots two days ago. Yesterday morning she was fine for a bit, ate some solids, and then was playing and cried out. Then all of a sudden went lethargic...almost like she passed out for a brief (but seemed soo long!) 10 seconds or so. Then she slowly came to and was fine for a while. After a rushed trip to the ped they determined she most likely had a breath holding spell. All was fine until she came home and threw up all over me two hours later. Then she slept half the day but was otherwise happy and fine. Slept (or tried to at least) next to her crib last night and she seems okay this morning. Any one else have a reaction like this to shots or have any ideas what it could be. Ped says she could just have a virus now but the lethargic moment was the scariest thing in the world and I don’t want it to happen again!
