Paltrow has two children - daughter Apple, 9 and son Moses, 7- with musician-husband Chris Martin.
"Chris and I would love a third child, but I don't know if I could start changing nappies again," said Paltrow.
The actress also revealed that she suffered depression during birth of Moses, reports mirror.co.uk.
"Also when my son was born I had terrible depression. It was strange because with my eldest it didn't happen. I was super-happy," Paltrow said.
"But with Moses it took me a year to get out of a hole," she added.
