Croup + Growing Pains = Lack of Sleep!

I have not slept a full night through for a few days now and it is catching up with me!  Blaine started coughing Wednesday and then barked all night long, even getting so that he was gasping and not breathing well.  I took him to the Dr. Thursday morning and he was diagnosed with croup.  The oral steroids they gave him helped with the swelling in the voice box and trachea and helped tremendously with the barky, raw cough and hoarseness.  But he still has a cough and not feeling great.  So I have been up with him at least once a night the past few nights.  And if that wasn't enough, we were up 3-4 times with Ava last night when she woke up crying because her legs hurt.  She has experienced this before and there is nothing we can do but give her some Tylenol and rub her legs for a while.  Chalk it up to growing pains I guess, but I hate to see her hurting so bad :(
