She Said What?

My boys are 4 and 11 and they seem to be very concerned lately about hurting their “nuts”. If they are playing ball and it comes anywhere near they’re groin area they grab themselves and proclaim “My NUTS!” I try to curb this talk, but I am clearly unsuccessful. Belle is 2 and she is in a Monkey See Monkey Do routine lately, so my petite, curly blonde baby hits her knee on a toy and she quickly grabs between her legs and shouts “ OH MY NUTS!”
