Mother-of-three Sarah Bartlett was left in "utter shock" when she received an anonymous card with £100 as a reward for being a good mum.

The card which she received last Sunday card said: "Darling Sarah, from another mummy who has noticed that you do an amazing job, enjoy the enclosed, for you. Be blessed."

The 37-year-old, from Sidcup in south London, who is mum to Holly, 17, Ben, ten, and five-year-old Georgia, said she initially thought it might just be a belated birthday card.

"But when I opened it, I started to cry with happiness", she said.

I am just so grateful and cannot thank them enough. It's not all about the money, it's the gesture which made me feel so incredibly happy. It made my week. Sarah Bartlett

Sarah also said the sender's decision to remain anonymous "shows how kind-hearted and selfless the woman is. She didn't want any praise from it".

"I literally have no idea who this anonymous person could be - I asked my friends but they told me they didn't send anything."
