We recently moved into a condo on the second floor. The balcony has rails that are wide and unsafe for our 7 month old who is learning to crawl. We would never let him out by himself but, we still want it to be safe. Someone suggested getting chicken fence and putting it up w/ twist ties… Any other suggestions? Whats safe that he won’t be able to crawl up onto or pull down or even bite on and hurt himself?
