This is the dramatic moment a quick-thinking mother saves her baby with the Heimlich manoeuvre.

The three-month-old baby was choking while being carried by her grandmother after drinking milk in Suzhou City, Jiangsu Province, China, on April 8.

Footage shows the mother, Ms. Zhu, laying the toddler on her side and patting her back.

She then placed the baby on her lap and performed the Heimlich manoeuvre for 30 seconds.

Fortunately, the baby cried out again, relieving the family from the situation.

Ms. Zhu said: 'I was so nervous that I could only rely on my memory to perform first aid, and my technique was not quite standard.'

She also reminded parents to ensure they know first aid for medical issues that can arise in their family.
