Describing the stranger as "harsh" and "nasty", the woman said they needed to get their facts straight before judging others.
"Yes, I have a double pram in my car! Yes, I have two baby car seats in my car," she told Daily Mail Australia.
"The point is, don't jump to conclusions if you don't see me push a pram or hold a baby as I dropped my husband off at the entrance with the kids while I went and found a car spot. People are so nasty and quick to judge."
You can't actually be fined for parking in a space reserved for people with prams.
They're often made available by shopping centres to make it easier for customers with small children to access their services.
But discourteous motorists have been slapped with warning stickers after parking in the reserved spots.
In 2018, Brisbane City Council parking officers placed a sticker on a vehicle in King George Square car park with the notice "This car is illegally parked".
A spokesman for the council told the Courier Mail the driver was not fined but "issued with a warning sticker".
A police spokesman said there was no regulated penalty for parking in a space designated for parents with children requiring prams.
Parking in an area for people with disabilities is illegal.
