My neighbour opposite has young children, I sympathise and understand kids that age are going to make noise, it’s just what they do.
However every single weekend for the past 6 months since then moved in (and I imagine most of the summer hols) the neighbour has been letting them play out in the front garden from 6am or getting them in the car and they just scream full pelt non stop.
It’s right opposite my bedroom window, they wake me up and I can’t get back to sleep.
I am absolutely sick of it. They are council tenants can I put in a noise complaint? I have mentioned it to the mother before and she didn’t seem to see the issue using the excuse they’re little. 
This morning it was from 5.45am.
