A social media mum has gained a lot of attention for her genius sensory play hack.

TikTok user @elleannachristine created a faux sand pit for her infant daughter to play in using a popular brand of cereal.

Half-filling a NutriBullet food blender cup, the video shows Elle blitzing a portion of Cheerios into a powdered substance that closely resembles sand.

She then repeats the process several times working her way through the box until she has enough 'sand' to fill a large kitchen tray.

The mum then adds a selection of sand moulds for her child to play with before placing her daughter on a towel to begin her sensory playtime.

The clip was posted on TikTok - a video social networking site - two days ago and has already received 338k likes.

More than 3,400 TikTok users posted comments underneath the video - but feedback was varied.

One user praised the mum writing: "No one said you were allowed to be this smart," followed by a series of love heart emojis.

Another posted: "Well if this isn't the most genius thing I've ever seen..ti [sic] bad my youngest is 6 now lol."

But others weren't convinced.

"Isn’t she going to be trained that all sand will taste like Cheerio dust now?" was posted by a user questioning the hack.

And others agreed, commenting: "All fun in games till you take her to a real beach and then- (but this is a great idea)."

Chiming in to settle the debate, one woman suggested that there's nothing to worry about, by posting: "PEOPLE... Kids try to eat everything.

"We all drink water but understand to not drink toilet water, public pool water, salt water, etc.

"They learn."
