This baby woolly monkey is just five days old. He was born at Monkey World in Dorset but is being brought up by staff there because he was unable to feed from his mum.
Here he is with his human carer Alison. He needs to be fed every two hours, a bit like a human baby.
It's hoped he will be introduced to his real family when he's a bit older. But at the moment he's happy being looked after by his foster mum!
But when he's not eating or hanging out with his carer he spends the rest of the time napping on his heat pad!
