Elderly neighbours complaining about kids playing

[LonelyJemma]

I live near a mixture of bungalows (all council owned), houses (private rented) and flats (mixture of both) and I'm having issues with a couple of elderly women (1 on one side of the road and 1 on my side) I live near a block of communal flats and my kids play on the grass in front of them and near the bungalows (where one neighbours grandkid stays over sometimes) the kids are doing NO harm to anybody. No anti social behaviour, not being overly loud, no trouble caused but yet these two women are complaining about the kids playing near their home. I personally don't see the problem, unless they're causing criminal damage to their properties or chucking things over the fence, etc. Which they're not. They are primary school kids playing out, enjoying the nice weather and having fun. These neighbours are sending my blood pressure through the roof, I'm annoyed they are telling my kids to stop playing or "play out over on your side"
I don't have the confidence to confront these women and give them a peace of my mind. I've contacted the council to ask them if the grass these kids are playing on is council owned or private. It gets cut by the council so I'm assuming it's the councils. Am I in the wrong for allowing them to play on council owned grass? Am I wrong in telling my kids that they are allowed to play where the hell they want as long as they're not causing trouble?

How funny that there’s a thread asking if the UK is anti children whilst this one is going.

Yes, but a conversation between adults is much more likely to yield a workable compromise Francis. The neighbours don't own that bit of land and OP is under no obligation to stop them playing there but it would be neighbourly to try to find something everyone's happy with and that's probably beyond 6 year old kids, hence OP needing to speak to the neighbours herself.

The neighbours haven't said the children can't play on the green at all, just asked them to play on their own side. Why can't they do that?

My road is on a slight hill. A few summers ago, some children further up had some kind of wheeled toy, which they used to run down down the road with, screaming as they went. Over and over again every evening. My house was the point at which they stopped, so I had the noise not just while they ran past, but while they turned round. My elderly neighbour wears a hearing aid, and his wife told me the little girl's screech was so piercing, it was quite painful for him.
