Our dearest JJ has his yearly doctor check up. He is now 5 and had to have a DPaT booster. He has had 4 of these already in his life. This is the first time though that he has had a reaction. It is still in the category of what the doctors call a 'mild' reaction. But it is worrisome. We are having him sleep in our bed tonight to make sure nothing happens overnight. He has a huge red welt and swelling at the injection site. It is about the size of a baseball and hot to the touch. He is not running a fever though. I gave him so motrin for the pain and swelling. Please pray for healing and that the reaction will not get worse.
