Whether you’re dealing with an unsettled, crying baby, a tantruming toddler or a moody school-aged child, a mum-of-two has a piece of parenting advice which she swears by.

Jennifer Batchelor shared the pearls of wisdom to Instagram and it’s simple yet so effective. “Put them in water or take them outside,” she began her post.

“It was the first useful parenting advice I ever got.” ⠀⠀

Jen goes on to ridicule a piece of advice which new mums are often given.

“Sleep when the baby sleeps”? I think the polite word for that gem is poppycock. But this particular axiom has saved me many times over,” she continues.

With her eldest son now nine years old, Jen says it was in the hazy newborn days when she couldn’t settle her baby and she phoned her mother at breaking point.

“I don’t remember how old Nathan was when I called my mom in tears because I couldn’t stop his, but his age was probably measured in weeks. Maybe days,” she explained.⠀

“Nothing is working; I don’t know what else to try,” I sobbed. “He’s not hungry or sleepy or wet.”⠀

“Try giving him a bath,” she suggested. “Or bundle him up and take him outside for some fresh air. I always say to take them outside or put them in water, and usually the grumpiness goes away.”⠀

Jen says this simple piece of advice has seen her through every stage of parenting.

“It worked that day, and it’s worked many times since. We’ve done baths at 10 a.m. I’ve paced our driveway with a baby in my arms at 2 a.m. And today, at 5:15 p.m. when my children were fighting for the 17th time since they got home from school and I was about to lose it, instead I put one in the bath and I sent the other outside and now maybe all three of us will survive until Dad gets home. ⠀

“Almost nine years later, it still works,” she says.

Jen finished off the post by urging other parents who are struggling with whatever age and stage their children are at to give this advice a whirl.

“I can’t give you advice about sleep schedules or feedings or Montessori-approved toys. I don’t know what we’re gonna do about Tik Tok and Snapchat in a few years. But when they’re falling apart at the seams for no apparent reason, take them outside or put them in water.”

And the best bit? Jen finishes the post, writing: “Oh, and it works on grownups, too.”
