Going back to the OP:
"Her and her husband have a crazy fascination with keeping the house like a show home and nothing else seems to be of importance other than that. I cant emphasise how much of a fascination it is"
What I don't understand is how she can say this when she quite clearly says in a later post:
"The thing is I dont get to see friend too much and often what I do see is "
So, if you don't see someone very much (she says in one of her posts that she won't see her again for a couple of months now), how can you know that her & her husband have a crazy fascination with keeping their house like a show house ?? Perhaps they just like to make sure it is clean & tidy before visitors come. She also doesn't elaborate on what exactly is so shocking every time she see's this "friend".
She also says:
"no baby gates allowed"
Well, as others have said, some rental properties do not allow you to have baby gates. I can understand why, as my house has really flimsy plasterboard walls & the gate at the bottom of my stairs has pinged through the plasterboard, making an unsightly hole in the wall.
"children not allowed toys anywhere other than their bedroom"
Does she know this for a fact? She doesn't say. Maybe they are allowed to bring in one or two things at a time like I was as a child but have to keep them stored in their bedrooms. Fair enough as far as I'm concerned.
"children not allowed to sit on the expensive leather sofa if they are wearing clothes with buckles and belts etc"
It's not like they're not allowed on the sofa at all is it ?? A few months ago we bought a new leather sofa that cost us £3000. I'm sorry if it makes me a bad mother, but I do not allow my kids to wear belts or buckles on it either as I cannot afford to replace it or get it repaired should it get damaged, and tbh why should I?! It's not often they wear things with belts and buckles at the age of 2 anyway is it??!
She also describes this woman as her friend and in her next post she says:
"she is a friend and I wouldnt want her to go through any heart ache"
But then when she is asked why she would even consider doing this to a friend, she backtracks & says:
"She s not the kind of friend I would ring to have a chat with, she s a distant friend. It is my DH and her DH who are the friends really."
As for the rope on the door handle at night. Personally I wouldn't do it, but I cannot even begin to see why anyone would see this as abuse. As I said before, I had a hook & eye latch on DS1's door for a couple of weeks a few years back to stop him coming out of his room at night. Should I be reported too ?
She said she doesn't see this woman very often, it will be a couple of months before she sees her again, so on average probably only sees her 5 or 6 times a year max. How the hell can she make a judgement about someone & how they are with their kids & whether or not there is some kind of abuse going on from that little contact?
IMO, calling the woman's HV is a major interference & I would be so angry to think of any of my so-called friends doing this just because of the few things mentioned in the OP. If there were serious, genuinely serious, concerns of child abuse, then yes, report the person concerned, but as far as I can see, there is nothing that jumps out at me as a serious concern, just a different way of living and parenting.
VicarinaBooTu - I can't begin to imagine what you went through as a child, but your situation is entirely different.
You said yourself, people heard what was going on. The children described by the OP are not being beaten, there is absolutely nothing that is apparent child abuse from what the OP has described, unlike your situation. Please bear that in mind.
Just because most of us haven't been through it, doesn't mean we would just sweep any concerns under the carpet, but they would have to be based on what we know, not just what we assume, like the OP.
(apologies for the length of this post. Got a bit carried away! )
