@Jim472 I also have on my listing, not suitable for 0 -2 but tbh it is Ok for non-mobile babies and not for toddlers 3 - 5 (or older) if unsupervised. Not sure Airbnb have the age group suitabilities right.
I like you, do detail that it is not suitable because , no stair gate, unguarded heater, kettle at accessible level etc. and again " must be supervised at all times" - and that is without a pool, dock etc.
Being near open water and children not being supervised who also terrify me @Jaye6 (I do open water swim and the dangers are real!).
I don't have instant book and I question parents of children more before accepting the booking. I have had several children stay and the parents have been great and the odd decor in my home has kept the children amused. The set up is a good family room for well supervised/behaved children and I would like to welcome more but it is scary.
I make it very clear that I expect adults to be responsible for their children and the potential problems but I do still worry about accidents happening - it is natural too (I did work in A&E too though).
