I dunno, I have been on the other side of this issue, but only in one house of all I have ever visited, with two kids and a step. I was invited to stay in a home of former in-laws, the female head of household had chosen to have no children and doesn't like kids overmuch--to each one's own. My son was about one year old and into everything for a whole weekend and it was sheer torture to constantly manage him as there were expensive breakables all over the house at his level.
This would have been difficult but tolerable in itself, but the woman kept asking me in a confrontational way why he wanted to touch things and why he couldn't just sit still etc. Ugh. Because he was a toddler, that's why, lady. Gimme a break. I explained to her that in most homes we visited, people had kids, so the places were reasonably childproof. She had never even heard of child proofing. And was offended. Good times.
