“The apartment is the ground floor of our family home. From the end of July to first week in September our children will not be home, most other time you may see and hear our small children, we have put precautions in place to limit noise travelling from our apartment to ground floor apartment. However you may hear the pitter patter of tiny feet, our children playing in the back garden (not early in the morning though) and some normal kid noise”

I also read that they are also now having a new barrier sound deadening door fitted between the two dwelling spaces. A bit late for your sanity at this stage. Must have been awful.
