Neighbour reporting me to the council for anti social behaviour

[Smile345]

I'm so stressed and anxious, not slept or eaten in days. We live in a semi detached property. Two children, one a toddler. My neighbour has complained numerous times over the past few weeks about noise.
My husband making a lot of noise leaving for work at 6.30 am, I assured her I would ask him to be quieter. He literally creeps around now. Another complaint, my daughter was like an 'animal' using the stairs, I have now put a baby gate up so she cannot use them. Another, we're banging/slamming doors in the early hours (I have no idea what she's talking about), we're a busy family and are in bed by 10pm! However, I've put door silencers on every single door.
She is incredibly rude when she has knocked the door, making out I'm a bad parent. She's an older lady and a widow and I feel like I've genuinely tried my best to resolve all issues.
I'm terrified of what the repercussions from the council will be as I don't know what else I can do. We both own our homes. Also, it's likely that at some point one of my children could wake during the night (nightmare/illness). Any advice greatly appreciated.
