MMR on Wednesday. Very tired and clingy

Otherwise fine, but he is having 2 2 hour naps a day instead of one and is very clingy. Is this an MMR side effect as we are at the grandparents and it is causing fierce debate!

possibly - 4 days after the vaccine might just be the time when the vaccine virus has multiplied enough to make him grumpy. Usually this happens after 8/9/10 days though. Hope he feels better soon!
