My six year old daughter is constantly taking over my husbands and my position as the parent of our 2 year old daughter. She constantly has this need to check on her, boss her around more in a way that we should be doing with our 2 yr. old, she tells my husband and I that it's time to go and see what my daughter is doing in the other room and makes it her business to go and do so. It is driving me insane. She literally parents her. I have no clue on how to handle this appropriately and effectively. What advice can you give to us?
