Should I worry?

We have never lived in a house with stairs before so we have never really had baby gates. . .but I am thinking that I might actually need to go out and get some.  Seems little Ben has discovered our stairs.

This little man is going to give me a run for my money.  I have never really "baby proofed" before either.  Mac and Kate were never curious about what was behind closed door and drawers, however, Ben is a little more curious!  Oh, well.  Keeps this mama on her toes.

I might need to call in some help!
