Parenting Reverse Psychology

My daughter is about to celebrate her 9th birthday and I know this is going to cause some issues with the 12 year old son who thinks she gets too much attention already. (They get equal attention but you know how kids are). So, this morning I attempted a preemptive strike with individual discussions with each of them:

Me to the daughter: “I know it’s your birthday weekend but that doesn’t mean you get to be queen and act all snotty to your brother, OK?”
Her: “OK Daddy.”

Me to the son: “You know its your sister’s birthday weekend so she is going to act like a queen this weekend so don’t get upset when she does. You’ve already had your weekend OK?”
Him: “OK Dad.”

I guess I’ll just have to wait and see how it goes 😉
