Cry It Out:
When Is It A No-No And When Can It Work?

When is Cry It Out not safe at all? At what age can you start? When does it actually make sense?


Crying It Out methods, sometimes called ferberizing, are not safe for newborn, young or sick babies and usually not successful at that age. On the other hand, there are some situations where you could consider it.

Having looked at the pro's and con's of crying it out, you may decide to give baby sleep training a try. To make the most of it, check the two lists below: when is crying it out a clear no-no and when can it actually work.

When is Cry It Out a no-no

Sleep training your baby with a Cry It Out method will not work and may even be harmful for your baby when:
  • Your baby is a newborn (!!)
  • Your baby is under 6 to 12 months, depending on maturity (see below)
  • Your baby is ill, whether seriously or just having a cold or teething - read the infant sleep problems pages for help
  • You know your baby is in pain, is afraid or hungry
  • Your doctor has disadvised crying it our for any reason
  • You, as a parent, feel lightly or seriously depressed (post natal depression/baby blues)
  • You do not believe the crying will help your baby sleep better
The reason for not trying letting young babies cry to sleep - apart from they are not strong enough mentally and physically - is that before six months their sleep patterns are just not mature enough to be messed about.

Erratic as they may seem, the development of baby sleep patterns is crucial for your baby to reach good sleep habits. In this case it is not the sooner the better. Allowing the natural sleep patterns to develop, with guidance but without forcing, is most effective.

When can cry it out work?

"At 18 months old, I realised that my daughter was playing with me. She was totally fine, did not need night feedings anymore and had learnt to soothe herself to sleep quite well since she was eight months old.

Now she suddenly refused to go to bed and we spent hours before she would settle down for the night. It was so clear to me that it was all acting. I was so certain of that, that I did let her cry at bedtime (something I always said I found a cruel thing to do).

I made clear rules about bedtime and routine, gave her all the hugs and attention in the world. But I was firm: time for bed meant quiet time in her bed.

I think my determination must have been clear: she only fussed a bit the first night and then went to bed with a smile every night after that.
"

This is a situation when crying it out can work:
  • When your baby is old enough and 
  • You are convinced that she is not crying because she is afraid, in pain or hungry. 
It can be a very thin line between just being cranky and really having a problem. But as a parent, follow your instincts to decide when and if crying it out is right for you.

Also, before cry it out can work, you will want to have the basics in place: 
  • A bedtime routine
  • A baby sleep schedule 
  • A safe sleep environment 
  • Clear rules about when and where baby is sleeping.
Without these, you cannot expect your baby to sleep well.
