Jekyll and Hyde

Nate was unbelievably charming this weekend.  It started with Shabbat dinner on Friday night and never seemed to end.  He ate well.  He was energetic, playful, and even walked when we asked him to and rode in the cart (dum dum DUM) when he didn't want to walk.  He took his medicine, cooperated in tooth brushing, and occupied himself while Dave and I did some cleaning.
So why did Dave and I come to Monday morning feeling like roadkill?
Because for reasons we can't exactly explain, Nate had a pair of really bad nights.  Saturday night, moments after Dave and I fell asleep (literally) we were yanked from sleep by a screaming Nate.  I scooped him out of bed and what ensued was "Exorcist" minus spinning head.  He threw up more and more forcefully than he has in a really long time.  When he, and I, and the floor, and the nursery chair, and a bath towel were all covered, he settled back in my arms and said "Yellow spill make Nate's tummy all better."
After the clean-up and the debate over the culprit (white buns made in a facility that also processes sesame seeds or Olive Garden noodles which we had previously confirmed to be safe - It's really the only reason we go there) we all manged to sleep through the night.
Sunday, the case against the noodles became firmer when he developed a hive on his cheek while eating his leftovers.  Sunday night he didn't throw up.  He just cried and writhed in my lap for 30+ minutes crying about having a yellow spill and heaving but not actually succeeding in making his tummy all better.
We're blaming Olive Garden and now that the gift card is gone, we are unlikely to go back - ever, but it's just a guess.  I hate when he is sick.  I think it's almost harder now that he can tell us what is wrong and I still can't fix it.  He cries "Mommy hold you" over and over again, but I am holding him.  It's just not making things any better, and that breaks my heart.
Maybe there's no food to blame.  Maybe after a 6 week honeymoon, he's just having an EE flair.  Sure he takes the medicine and seems to be so much better, but it can't be just that easy, can it?  (If it was, when you decided to start a running program you wouldn't skip and entire week because of a bad cold, a bad call, and a grant deadline and then have to drag your tired self through a Monday morning run wondering why you let yourself backslide - but more on that later.)  Kids who take their controller meds still get asthma flairs.  Maybe when we kept him home from school last week for an almost identical pattern on Monday/Tuesday, we weren't preventing the spread of disease, but just missing the obvious.
Maybe it is just a reminder that even when things seem to be going smoothly, parenting was never meant to be easy and we were never meant to sleep through the night.
