A paediatric consultant has urged of to try out her go-to "100-second rule" that she swears makes a "huge difference" when it comes to getting their little ones to drift off independently. As any parents of young children will no doubt know, just when you think you've got your baby to , it's sometimes not very long at all until their cries let you know they've woken up once more.

Fortunately, there are things you can do to help your child get back to again, as explained by sleep consultant Lily, who encourages new parents to give her "respond versus react" method a go.

In a helpful clip shared viaLily, who goes by the username @dreamcoach, advised: "Parents, when your baby wakes up and they haven't slept for very long, I want you to do just one thing.

"I promise this one thing will make a huge difference in them settling back to sleep and learning to fall asleep independently."

She then revealed: "All I want you to do is watch the monitor and I want you to count to a hundred. Don't go in if they're fussing, just watch and respond versus react.

"It's normal for babies to wake up. They just need time to put themselves back to sleep. So giving them even just a hundred seconds can make a huge difference and it's likely they will put themselves back to sleep."

Lily, who also shares handy sleep content on under the username @lilbabysleep, added that parents can start trying this hack with babies of "any age".

This video has been warmly received by many exhausted parents, who have thanked Lily for sharing her wisdom and vowed to give it a go for themselves.

One person approved: "We did this and boy what a huge difference. 9/10 [times] it works."
