Parents will know the hardship of getting a baby to sleep, the night is full of singing, swinging and pacing.

But the mothers claim to have found a genius way to soothe their children without making them tired-and all you need is a toy fish.

A dancing fish, usually sold as a cat toy, is praised by many parents as the answer to a good night’s sleep.

There is a motor in this fish that can make the toy flap its tail. Mothers tie it to the child to provide constant pat and comfort.

Ryann Johanningmeier (Ryann Johanningmeier) shared a video on TikTok showing her baby and the fish gently tapping his diaper.

The 23-year-old man from Florida captioned the video: "TikTok let me do it. Let him sleep well."

She later confirmed that she used the toy to put her baby to sleep and then removed it.

John Ningmeier added: "I didn't let him sleep like he did when he fell asleep, I carried him in the cradle!"

Her video has accumulated more than 16 million views since it was shared on Saturday.

The tip has been widely circulated on TikTok, and the good thing-Jackson posted a similar clip on her page last month, which has been viewed thousands of times.

It shows a baby napping next to them, the fish being held in their pants and patting their diapers.

She shared another clip, this time using oven gloves to fix the fish in place, and she also added a sunflower flashing, singing and dancing as entertainment.

"You can't sleep without music," she explained.

He had to be slapped to sleep. Is the same with your child? #fy #foryou #children

Although mom @enjoy_266 also uploaded some clips of toddlers taking naps with the help of fish.

"He had to be slapped to sleep. Is your child like that?" she asked in a video shared in April, which has been watched nearly 5 million times.

She also shared a follow-up video of her little child falling asleep, where one fish slapped their diapers while they held another fish in their arms.

"The best gift for the children," she admired.

Although many stores across the country may sell this toy, Amazon also sells a variety of fish designs in its pet area for as low as $5.

Parents are crazy about this tip on the Internet, and John Ningmeier's video has accumulated countless comments.

Desmi Anderson commented: "I saw this on Facebook and said the same thing."

Timothy Huynh admitted: "I want to buy this."

The dog groomer’s life commented: “I wish I saw this 8 years ago.”
