Baby was up ALL night!

We are so tired today.  Last night, Shawn went to bed about 10 pm.  We went to bed at 11:30, and as soon as our heads hit the pillow, he woke up crying.  I tried just giving him the pacifier, but it didn't work.  I went back in his room and he was wide awake with his toes in his mouth.  I figured I would just hold him for a few minutes and he would fall back asleep.  Not quite...hubby and I ended up taking turns holding him until 4 am.  I finally went back to bed.  I guess he finally fell asleep around 5 and was back up at 7:30!  We are going to immediate care today...he has the worst cough and he's congested.  Why does this stuff always happen on a WEEKEND when the doctors are closed???  He literally JUST got over a cold a week or so ago, and now it's back.  He even had 2 doses of antihistimine, which normally makes him SLEEP.  I think mommy and daddy will be taking turns taking naps today!  Figures too, we had a million things we wanted to get done today and we are just too tired now.  Ho-hum...
