How do you babyproof the railing and banister? Our slats are technically out of code but we grandfathered in since the house was built in 1990. They are only 4-5 inches apart but still... We can't afford to redo the railing just yet so until then I want to make sure LO can't get her head, legs or arms stuck. I have seen plastic sheets but I am trying to avoid those. Ideas? Is it possible for them to still look decent or I stuck with cheap lattice or plastic?

We have a little bit of time since she isn't here yet so obviously not mobile. Just planning ahead.
