I have built some internal gates in my home to restrict that areas my dog gets to. Not having rug rats any longer, and using the gates only in my own home, I designed a Chinese Chippendale looking gate with no concern about the opening size. But a few people have asked for copies, and I'm wondering what safety concerns there may be for kids getting their heads stuck in the openings.
I can't find any publications on the CPSC web site, other than crib slat spacing (2-3/8") or bunk beds (3-1/2"). But aren't there some more general architectural safety guidelines I should follow?
