Barely surviving DS's 2nd bday

This is not how I wanted to celebrate my son's 2nd bday.  I was up late last night working on decorations/party favors/presents/etc for my son's 2nd bday.  I go to sleep and 45 minutes later my daughter wakes up not being able to breathe again.  She had croup in August and never fully recovered.  Off to the ER we go for steriods and x-rays.  We get discharged around 4am and she finally goes to sleep a little after 5am.  5:30am DS wakes up and takes off his pj's.  I go in there, put them back on (b/c it's cold and we haven't turned heat on yet).  By the time I change him, read a story, and sing a few songs, it's 6am and I'm back in bed with DH, DD, and 2 dogs.  6:45am DS is up again taking off his pj's and DD wakes up asking to watch My Little Pony.  I get DD and DS downstairs and turn on whatever the hell is on.  I can't sleep because kids keep fighting over what they want to watch.  I finally wake DH up at 9:30am on his day off.  I'm on 2 hours broken sleep.  I got more when I nursed a newborn!  I'm exhausted and so is DD and DS.  Happy 2nd birthday, kid!
