God help me... the little girl I babysit is 3 months old and she has screamed since she got here at 7am... my son is grouchy and doesn't want to nap... I have a whole house to clean, clothes to wash, and dishes to do... the little girl doesn't leave until 4 and I have to be ready to walk out of the door for this semi formal Christmas party at 5😭 I need a maid and a nanny for a day....
