Should I Be Worried?

Should I be worried that at just over 3 years of age he still thinks I can't see him if he can't see me? It's still too cute to care.

G in a muffled voice: "Come and find me momma!"

Me: "K. Where ever can my handsome boy be?" (seeing him immediately) "Hmmmm, could he be over here by the door? No. Over here by the table? No....." (as I grab the camera on the fridge right next to him)

G still muffled: "I'm on the floor!"

Me: (snap picture and then tickle foot) "I found you!"
