Bless her heart.....again, it's not her fault! It breaks my heart for children without parental guidance. It probably would be a true Blessing & maybe something she will take with her forever if...............today, you make a pampering party for your daughter & her to camouflage what you are truly trying to do. Tell your daughter, you want her to take a shower & give her some of your pampering products (perfumed bath gel) lotion, wash her hair, etc. Then for her friend, as well. Maybe then help fix their hair, paint their fingernails, to make them both feel "special". This little girl may never have had this feeling. I think she will take this specialness home with her.
It's worth a shot!
