Update

After Bobby conked out in the car on the way home from A2, we tried to get him up for dinner and play before a later bedtime, but he would not engage, so he went to bed in his day clothes with no dinner :(  And he slept until almost 4am.  Then we played until 6am when he went down again for a good bit.  The spots were much less pronounced today - like a bite fading.  Still there, but not red or barely pink and not raised.  He was in a good mood, but not eating.

But as the day progressed, his mood got a little worse and he was pretty testy and overall blah. We ran some errands and went for a bike ride and walked around, but he was up and down until dinner time then it was all down.  We went out in the neighborhood again and it was fine, but he just started wailing after his bath.  Not hurt or wanting something or getting in the carseat or not liking getting dressed (-all why he usually cries).  It was so sad.  And it seems the bumps are back.  Not as many, but there are definitely some new ones - other side of his chest, some more on his legs.  Face and chest are clear though.  Back is much better.

So I'm a little worried,  Rick and I aren't totally convinced it is a drug rash.  But who knows.  I don't think it's bed bugs because I haven't seen any (bugs, blood, skin or bugpoop) on his white crib sheet, but you bet I'll be looking for them anyway in the morning. And Rick and I don't have anything like that and I don't think they would come from Rosannes pack and play or through our walls somehow.  The proximity to taking the antibiotic is just too close.  I'm doing a lot of web research and looking at a lot of nasty rash photos.
