A Brisbane mum was shocked to discover a handwritten note along with $5 inside a tin of baby formula.

At first, Tillz Siofele thought it was "strange" but upon closer inspection the young mum said she was heartwarmed by the message.

Siofele was in need of milk powder for her little one and had sent her husband to buy the product last week.

She opened it days later to find the money and note inside.

"Enjoy this little something. Happy wealth Wednesday," the note read.

"I saw a note and thought 'this is strange'. I unfolded the note and there was a $5 note clipped to it," Siofele said.

Her husband was also baffled by surprise gesture. Hoping to get answers, Siofele took a photo of the note and shared it on Facebook.

Some people suggested the gift may have been left by Camira local Susanna Lucy, who was known for leaving small surprises in groceries, the Courier Mail reported.

Lucy later confirmed this to be true saying she and other mothers who live all around Australia often make an effort to leave anonymous gifts just to make someone's day.

"There's not enough of that sort of stuff that happens. I get a lot out of it too obviously," Lucy said, adding she has been leaving small gifts for other parents for about six months.

Her reason? Simply to make someone's day.

Siofele said she will keep the tradition going.

"We don't need it but we can pay it forward, and the next person might need it."
