Baby Amara was born at Queen's Hospital in Romford, Essex, on August 3 weighing 6lbs 3oz.
Single mother Onyi, a student from nearby Chadwell Heath couldn't believe her eyes when her 3day old baby 'grabbed' her bottle during a feed and held it to her mouth unaided.
She said: 'She was crying as she was hungry and when we were feeding, she started shaking, then she just grabbed the bottle and she was holding it by herself.
'We couldn't believe it because babies don't normally do it that young, I'm so shocked that I have been documenting it every day. It's unbelievable, even nurses are really surprised - when my health support nurse came she was shocked as well., she couldn't believe that this could happen.
'Whenever we go to appointments, we take pictures of her doing it.
The midwife and even the doctor we had an appointment with on Saturday was actually amazed - they all couldn't believe it.'
She said: 'I just think she has a lot of strength, I'm not sure why though as she wasn't particularly heavy when she was born.
'When she doesn't want it she will push it away.
'She isn't strong enough to throw it away, but she does push it away, like she does with her dummy.
'If she is really hungry, she starts shaking, then she will just grab the bottle as you give it to her.'
