Had a few days away very recently and we picked a cottage that had a huge garden so that the kids can play out. When we arrived the woman who owned the cottage (lived next door) was very irritated with us because we hadn't told them that we had a young child with us (age 3). The reason being the garden had a stream in it. When I say stream, it was a man-made trickle that went down the garden, like a water-feature/bamboo affair.
We said 'no problem, we will be very careful'. When we went out to play the little one had to hold our hand the whole time, but we did let him put his hand in the trickle (never without us holding his hand or body). On the second day the woman came rushing out of her house shouting at us for letting our 3 year old into the garden (even though I was holding his hand). When I explained to her that we would will always hold his hand whilst we were out there she insisted that we were not allowed to play in the garden.
I know it was for good reason, but there was no mention of the stream in the advertisement, and her response was almost hysterical and aggressive. Surely bathing, taking children swimming, water play is safe as long as you are very cautious to supervise young children. It kind of spoiled the holiday a little because they weren't allowed to go out and play on the slide and swing because of scary, shouty woman.
I am probably being totally unreasonable, and just getting it off my chest really, but why have a stream in a garden you are planning on renting out to families if you are so anxious about children and water??
