The Chinese-Australian mother said she feels judged by other parents when she buys baby formula.

The mother of two said she feels the need to take her daughters Ava and Allegrawhen buying baby formula.

She shared a picture of a shop assistant standing next to an almost-empty crate after the group of shoppers wiped out the pile of about 50 tins, which retail for up to $24.70 each, last Saturday.

They have reportedly been unable to find Bellamy's Organic milk formula in Australian stores, but the product has been showing up for double the price on Chinese website, Taobao.

'I would like the government to intervene,' Ms Leung told Daily Mail Australia.

'Perhaps to make a register to limit the amount of formula one can buy - determined on the age and number of children that they have, at least until the shortage is over.

'The chemists should not hike up the prices either. Supermarkets should enforce the limit, at every store. I have been shocked to see those pictures of many boxes being loaded onto trolleys.'
