The back to school disease

We have had quite a week of illness.  Mr. 3's nose started running over the weekend which led to his typical wheezing.  Unfortunately it got worse and worse as Monday progressed and ended up with us in the ER Monday night.  Luckily steroids turned him around (and led to him sitting on the floor in the living room at 3am singing and playing cars while his parents lay on the couch and wished for sleep).  Mr. 9 had a cold last week and has a residual cough that is taking a while to clear.  And Mr. 5 and David both developed fevers and felt pretty terrible.  Mr. 5 seems to have recovered quickly but David is still down for the count.  Mr. 11 and I are the remaining hold-outs.  We're keeping our fingers crossed for good health!
