We put a few drops of peppermint oil in our bedroom humidifier and used Kid's Xlear nose drops before he went to bed. I also put him in his bouncy seat on the bathroom floor while I took a shower on Wednesday, and that seemed to really help break up the gunk. Of course, we also used a bulb syringe ("booger-sucker" in the vernacular) to suck out the goop. All of these things in combination were enough to help him feel much better, but I think the nose drops were the biggest help overall. Adam bought them (on Barbara's recommendation) at Harvest Moon and they seemed to dry Zeke up really quickly. He's back to daycare and his usual self!
