This is the adorable moment a four-year-old girl helps her little brother on his first day at school.

Jeena Chaisri walked little brother known as First, aged two, to school in the Lat Krabang district of Bangkok, on August 6.

The toddler starting at kindergarten and was understandably feeling shy - not talking with any of the other children.

But big-hearted Jeena sat next to him at dinner time and carefully spoon-fed him his lunchtime bowl of rice.

Teachers recorded the heart-warming moment and showed it to their mother Nuttana, 28 and father Ratchanon, 29, when they collected the children later that day.

Ratchanon said: ''Jeena is very close to First. She loves him very much and is very protective. We're so proud of them both.

''The video was very cute. It made us very emotional. We're very thankful to have two children who are such good friends.''
