Washington, Nov 19 Angelina Jolie has admitted that she struggled while breastfeeding her twins.

The actress admits she had to stop suckling newborns Knox and Vivienne after three months - because breastfeeding them became a huge chore and she was exhausted.

"It was about as much as I could do," Contactmusic quoted Jolie,as telling U.K. TV show GMTV.

"There's this football hold - it's a lot harder than it looks in the books. I did that a few times. I would take turns. It just takes a long time," she added. (ANI)
