"Chill Out..."

Tonight going through our normal bedtime routine, Ryah caught me off guard and I was left speechless!
Here is how the conversation went down:
Me:  Ryah, lay down now so I can cover you up.
Ryah: (looking around her room for all her barbies she wanted to sleep with) Mom, where is my "tangled barbie?"
Me:  Ryah here she is, now hurry up and get into bed
Ryah:  Mom... Chill Out!

Oh boy- where did my sweet, innocent little girl learn this?  All I could do was laugh to myself and think... It has only just begun!
