As a baby, my little world isn't all that big. Basically my world consist of my house and the neighborhood I live in. Thus, it is very disturbing that I hear there are burglars who are sneaking into houses near where I live and stealing things. Would they steal my Baby Einstein?!?! Or Me!?!
That is why I am giving my full co-operation in protecting the house. I can't own a gun but I can yell very loud if someone a don't trust comes into the house. Yell first, ask questions later.
Defending the house from intruders is a responsibility of the entire family. Even the baby.
