It's the question that has plagued philosophers and academics alike for millenia. Aristotle, Plato, Socrates, Descartes. Richard Dawkins, Christopher Hitchens, and Stephen Hawking too. They all pondered the same question and now, on July 31 2021, we finally have an answer.

The question? How many times should you wash your child every week. The answer, well twice is just about fine according to the experts.

The Holywood powerhouse that is the relationship between Ashton Kutcher and Mila Kunis sparked the debate just a few days ago when they revealed they only wash their young one when they see 'dirt'.

Mila explained:

I didn't have hot water growing up as a child, so I didn't shower much anyway... But when I had children, I also didn't wash them every day. I wasn't that parent that bathed my newborns - ever.

Ashton added:

Now, here's the thing: If you can see the dirt on them, clean them. Otherwise, there's no point.

While many agreed with Kunis and Kutcher, others were horrified.

One mother wrote:

I bathed four kids every day. Every. Day. I worked and didn't have money like they do to hire help. A lot of work, wtf!? That's your job as a parent to keep your children clean.

Many said that their approach was wrong, but alas the Gods have spoken, the Gods being Angela Spencer, a UK-based pregnancy, birth and parenting expert with over 20 years' experience.

Spencer revealed to FEMAIL, that their relaxed approach to washing their child is perfectly fine.

The expert confirmed that parents should wash their child a minimum of twice a week, however common sense is the main thing to remember.

More specifically, Spencer said:

If they've had a busy day, got dirty and in need of a bath, then have a bath. However, if you've had a lazy day, no one is really that dirty I reverted back to the "top and tail" scenario. That includes brushing teeth and hair.

Spencer added that over-washing your child can actually be problematic as their sensitive skin can dry out with water and have a bad reaction to the chemicals used in skin products.

And Spencer isn't the only one. The American Academy of Dermatology Association (AAD) also offers similar advice and says that children aged between six and 11 only need to be bathed a minimum of 'once or twice' a week, however washing them more won't do them any harm.

So there you have it folks. Don't stress. Take it easy. Let common sense consume you. And to the parents out there, just remember to wash your child twice a week.
