I can’t find anything online about how long the side effects might last. Ds has the vaccine a week ago and has been out of sorts ever since. He had random green poos etc for a few days and crying a lot and painful wind and past couple of days or so the painful wind/poos have increased. I feel like I’ve lost my happy baby. Has anyone else experienced this for so long after the vaccine? Could it be a side effect? He doesn’t have a fever any more after the initial day of having it.
