I'm certain it's just the vax b/c he was perfectly fine all day yesterday up until the vax. He slept for about 3 hours after that, then woke up screaming - his legs hurt and he had a bit of a temp. Now this morning, temp is back down (could be the tylenol, but it is down) and he is very much himself. I figure if he was really sick he'd be more clingy, he's in his bouncy chair as is our morning routine when I eat bkfst and shower. He's babbling, smiling, singing, etc. I'd say he's about 90% himself.
I could be wrong, but my gut tells me he's ok. I think if he picked something up at the ped's (which is very possible), he probably wouldn't even have shown signs yet. We left there at 5pm yesterday and it's only 9am now, I would think he wouldn't be symptomatic yet. The dr. said yesterday that he is perfectly healthy.
