A new mum was shocked to find a note left in her letterbox complaining about the amount of noise her four-month-old son makes. 

Tiffany, 36, said that she burst into tears after finding the message which had been typed on an A4 piece of paper by an anonymous local from Redcliffe, north of Brisbane. 

She shared a photo of the passive aggressive note which has gone viral and sparked a divided reaction on Facebook. 

'I'm writing this on behalf of your neighbours and wanted to reach out to you regarding the noise level coming from your residence, particularly the crying of your baby,' the note said.

'While we understand that babies cry and a newborn can be tough, we can clearly hear everything from the early hours of the morning, throughout the day and into the evening.

'The prolonged and frequent crying has disrupted your fellow neighbours. Some of us work from home and others are shift workers. We have tried closing our windows and doors and even have turned on appliances with the TV and radio and the crying is still being heard.

'We value being good neighbours and respecting each others' space but wanted to reach out and ask if it would be possible to close your rear doors and windows while the baby is feeling unsettled.' 

The note ended asked for Tiffany's understanding and appreciation in the matter. 

Tiffany told Yahoo News Australia that the 'unreasonable' note came as a huge shock and left her 'pretty upset'.

The Queensland mum explained that she, and her partner John, bought their first family home last year near a busy main road with a 'very lively' ibis colony and a 'reputation for hoons'. 

She hit back by slamming the note, saying she thinks the neighbours know how unreasonable it is to complain about a baby crying in suburbia, before going on to describe the struggle of new parenthood as 'challenging and isolating'.

Tiffany insisted that her baby was 'pretty chill', 'settles quickly' and doesn't scream throughout the night.

The young couple believed that there are better ways to go around the dispute and that 'we would have been open to a conversation. 

'When you read the undertones, you know the reason they’ve used that language is to cause guilt,' Tiffany told Yahoo.

'But I won't be closing my windows, and we're not going to lock our house up or muzzle our baby.'

The note sparked a divided reaction online. 

'As a new mum myself, this really hurt reading this. As if we don't have enough to worry about already,' one Aussie commented.

Another added: 'That person obviously has never dealt with a newborn.'

While many agreed that the letter as 'rude' and 'pathetic', others thought the neighbour's request was 'very reasonable' and 'well considered'. 

'It's not an aggressive letter or anything abusive or threatening. Even says he wants to be good neighbours,' an Aussie commented.

'I don't see any harm in it,' another added.   

Moreton Bay Council can investigate breaches of noise regulations in the home but locals are encouraged to try and sort out issues amongst themselves, saying people may not realise the noise from their household is affecting others.
