It's something every parent has had to deal with at some point - getting their sleeping baby to stay sleeping.
Now, one mother has seemingly solved one of parenting's most cryptic puzzles.
Laura Gerson, a mother from Essex, took to Facebook to reveal the genius hack that keeps her 11-month-old daughter waking during the night.
Laura claims that since she discovered the sneaky trick, she hasn’t had to come to her daughter's aid during the night for the past eight months.
Writing to The Motherload Facebook page, Laura wrote: 'Since my little one was about 3-months-old she's gone to bed with roughly 10 dummies in with her. Found that when she cried of a night all she wanted was a dummy then she'd go back off.
'Realised that if she had one to hand then she would just find it of a night, trial and error with her losing a few down the side but 99% of the time she feels around, finds a dummy, sticks it in and she's sorted.
'Haven't had to go into her of a night for about 8 months now... WINNING!!'
Thankful parents, as well as parents who have already used this genius tip, shared their praises on Laura's post!
'My little one loves his dummy and I am always getting up to put it back in,' one mother wrote.
Another mother quipped, 'Why did I not think of this?'
Although, this trick won't last forever - and Laura freely admits she is not looking forward to when the 'Dummy Fairy' comes to take them away.
