My 8 year old daughter goes crazy when she sees her 2 year old sister picking her nose. She runs into the bathroom and puts liquid hand soap all over my toddler's hands. If I don't wash my toddler's hand right away, my 8 year old begins screaming at me saying that she hates me. I don't know what to do. I've told her I would wash her hands the minute I see her doing it, but that doesn't seem to satisfy her. I'm at my wits end! Any suggestions?
