Davina Wright, 45, breastfeeds Willow, Connor and Summer a couple of times a day – though never in public because she doesn't like the attention it attracts.
And she said she'll continue to keep her kids on the breast for as long as they want it.
She said: "A breastfeeding relationship is between a mother and child and they are the only people who should have a say in how long it continues. The beauty being that every mother gets to decide for herself.
"I know that extended, or natural-term breastfeeding isn't for everyone, and that is okay. I would say to people if it's not for you then don't do it, simple as that."
Describing her routine to the Daily Mail, Davina, who lives in Hong Kong with her husband Jason, said: "They each have their own room and I go in to each of them individually and it is a lovely bit of one-on-one time.
"At three years old they are basically just fed to sleep, not that they actually fall asleep, it's more like 'fed to calm/sleepy'.
"In reality it is only about 10-15 minutes of their day, their hectic, chaotic, loud, busy, competitive, triplet day, where they get to sit quietly by themselves with mummy."
Davina said in the mornings, the three toddlers are very competitive as they battle for their turn.
It might sound like an exhausting exercise in juggling, but it's nothing compared to when the triplets were born – when Davina was doing 30-40 feeds a day.
She said: "I think the weaning down of feeds during the day was partly because we got so busy... there was play and stimulation and they just asked for it less.
"I really only say no to them now... when we are out in public. I say that we will wait until we are home for that now, simply because I am aware of how many eyes are on us."
Davina, who has two adult daughters from her first marriage, breastfed them until they self-weaned at 13 months.
She said: "I set myself the goal of two years with the triplets, not fully sure that we would get that far, and definitely not thinking we would still be going at three years old.
"But they are still happy with it and I am still happy with it and it works for our family so we keep going.
"It has been everything to their lives, it has slowly changed to being a very small part of their lives, and one day it will be a distant memory in their lives."
