When you’re small enough to care about little more than where your next banana is coming from, some things are very important.
And pretty near the top of the list is lots of TLC from Mum.
This baby orangutan and his mother were spotted indulging in a heart-warming – and very human – show of affection at the zoo where they live.
The sweetest moment came as the youngster lovingly stroked his mother on her head as she closed her eyes, their faces barely an inch apart.
They also cuddled cheek to cheek, the baby’s little hand wrapped tightly round his mother’s finger.
And the bigger animal also held up her son by his arms and then lay back to let him practise walking on her chest.
No wonder he gave her such an adoring look and seemed to pucker up his lips for a kiss.
These pictures were taken by Olga Dmitrieva, who was given unrestricted access to the two orangutan families living at Moscow Zoo.
She said: ‘Orangutan parents are very tender, especially mothers. Sometimes I think we could learn from them about how to care for our kids.’
