Three-month-old Neveah was born really sick, and she has a long road ahead.

“They’re really wonderful girls. They surprise us every day! It’s all just been them; they never told anyone,” said grandmother Charlie Perron.

These girls are passionate about the product – still, they’re sweetly surprised by generosity.

“Some people don’t buy the lemonade; they just give us money and walk away and say have a good day,” said Martinez.

Some customers leave a little extra, and some – a whole lot. Seems like strangers are truly touched by these sisters’ love.

“I’m really proud of both of them. Two little girls with great big hearts,” the grandmother added.
