A mother who survived the Boston Marathon bombing has had her left leg amputated after more than 18 months of 17 operations trying to save it.

Rebekah DiMartino, 27, has been in constant pain since the explosions ripped through her lower leg and hopes her decision will mean an end to the discomfort.

But she said the hardest person to convince that amputation was the right decision was her young son, Noah.

Since last April, Noah has bawled his eyes out at the slightest mention of me possibly getting my leg amputated.

We have explained to him over and over what a better quality of life I will have and the things I will be able to do again etc.

But the crocodile tears always come, leaving Pete and I feeling totally helpless on what to do. But this morning something pretty neat happened. As we were on our way to school he started asking me questions about my surgery next week.

I could see him trying to process everything I was saying, but he didn't seem sad.

Instead with the biggest smile on his face he shouted "that's so cool! I'm gonna have a part robot mom!"

You want to take a guess on who's crying now?!

Rebekah herself believes that losing what remains of her left leg below her knee will be a positive move.

"Even though my leg is being chopped off and I won't be able to walk for a while, it's still a step forward to me," she said.

"The fact that I was given a second chance at life that day is something that I will never again take for granted," she told NBC News on Saturday ahead of the surgery.

"If I have to lose my leg in that process, so be it, because I'm still here."

Her husband, Pete, has since told the US news network that the surgery was a success.

Doctors say Rebekah could be taking her first steps with a new prosthetic limb within three months.

If all goes well, Rebekah is even aiming to take part in next year's Boston Marathon.
