There's no magical age to stop breastfeeding your child. While the majority of mothers begin to wean around their child's first birthday, experts say there's no harm in continuing the process. Some moms—like these celeb mamas—extend breastfeeding until their child is ready to wean off. Get inspired by these powerful words from our favorite uber-boobers!

When it come to nursing, the Big Bang Theory star believes a baby should decide when he's ready to wean—not the mom. "I never, ever believed that I would be nursing a child over the age of 3. But now that I am, I believe when he is done, he will be done," she wrote on her blog. "I believe that he will not need to nurse before he walks down the aisle to greet his bride...and I believe that nursing is natural and beautiful and wonderful." Bialik nursed both of her sons, Miles Roosevelt and Frederick Heschel, until they were toddlers.

Perhaps the least risque of the Kardashian fam, eldest sister Kourtney is a proponent of extended breastfeeding for a pretty simple reason: Why not? She nursed both her son Mason and daughter Penelope past their first birthdays, even when not everyone in the K gang agreed. She told E! News, "I mean, everyone would say, 'It's time, it's time, it's time, come on.' I started to stop a little bit, weaning and all that, and I'm like, 'Why am I doing this if I'm happy and he's happy?'"

Known for being an outspoken vegetarian—and for that feeding-her-son-like-a-bird video that blew up the Internet a few years ago—Silverstone wrote "Nurse like it's your destiny" in her book Kind Mama. She caught flack when she was photographed nursing her son, Bear Blu, while the two were out for a walk, when he was 11 months old. She also started a milk share program to help those who can't produce milk receive from women who have an oversupply.

When Salma Hayek visited Sierra Leone, she was so touched by seeing a malnourished one-week old baby that she offered her own breast milk to help the child. She nursed her daughter, Valentina, well past 1 year old, and was open about how much she enjoyed the intimate connection between mother and child. "I'm like an alcoholic. It is like, I don't care if I cry, I don't care if I am fat, I am just going to do it for one more week, one more month, and then when I see how much good it is doing her and I can't stop," she told Style magazine.

Right from the very beginning, model and entrepreneur Miranda Kerr adored breastfeeding her son, Flynn. (Who could forget that gorgeous Instagram post her then-hubby Orlando Bloom shared a few hours after their son arrived?) When discussing nursing, Kerr said, " is the most natural thing in the world, and I love...the bonding time we have during these precious and beautiful moments."

"I know some children who have weaned naturally at two years, [and] some kids wean naturally a couple of years later," Morissette told Good Morning America. "I mean, it's up to every child." The singer left it up to her son Ever, who nursed past 2 years old. She also advocated for the right to carry breastmilk on a flight after having a scuffle in London's Heathrow Airport, where she was forced to throw away her pumped milk before boarding.

It's no wonder that Danica McKellar is a big fan of extended breastfeeding, especially with her natural approach to motherhood. The former Wonder Years star breastfed her son Draco until he was 2-and-a-half, but she supports any length of nursing. "You can breastfeed as long as it works for both you and your child, you know?" she has said in an ABC News interview. "For me it was 2-and-a-half, and for you, it might be 3-and-a-half or 3 months or whatever it is that works."

The model mama to baby Vivienne got the star treatment while breastfeeding her daughter. Remember that Instagram photo with her hair and makeup team getting her camera ready while 1-year-old Vivienne enjoyed her lunch? Awesome.

Preston told People what many mothers feel after breastfeeding their children for a while: "When I stop, it's going to be really hard on me. I love nursing so much." She kept going with her son, Benjamin, past 16 months.

While celeb moms might have more help than we do, they don't always want to pump-and-dump, either. Jada Pinkett Smith breastfed her son, Jaden, until he was 18 months old, and apparently, took him on-the-go to make sure he was fed. "That baby never even saw a bottle. He went everywhere with me—premieres, award shows. I would just find a back room and hook him up," she told Fit Pregnancy. Go, mama!
