I recently read an article in Psychology Today (http://www.psychologytoday.com/blog/moral-landscapes/201112/dangers-crying-it-out) that states that letting your baby “cry it out” is detrimental to babies. The “crying it out” method of getting your baby to sleep was developed by Richard Ferber, M.D. The premise of “Ferberizing”, as this method is also called, is that you put your baby in his crib awake. He recommends that you don’t start this method of sleep training until the baby is at least 4-6 months old. On the first night of implementing the sleep training, you would go in and check on the baby after 3 minutes, then 5 minutes, and then 10 minutes. He does not advocate picking up the baby when she’s crying, but instead patting her back. On the second night check on baby after 5 minutes, then 10 minutes, and then 12 minutes.
The article states that letting a baby “cry it out” can affect health, such as digestion, can lead to babies not developing trust due to their needs not being met, can lead to caregivers not responding to subtle cues their babies may be giving them, and can cause neurons in the brain to die, because “when a baby is stressed, the toxic hormone cortisol is released.”
The author takes the position that our ancestors didn’t let their babies cry, because if they did, they would become food for animals. Babies were held all the time and their needs were met.
As a parent myself, and as a professional in the field of child development, my belief is that it is okay for babies to cry at times. Crying is a baby’s form of communication. They have different cries for different needs, and we, as caregivers, learn what our baby’s cries mean.
Humans have evolved since our ancestral times, and holding our babies constantly is not necessary, or even possible, today. More often than not, both parents work to support the family. Sometimes there are other siblings to care for as well, and we are not always able to meet their needs instantly and hold them. There are other times when we don’t know what the need is until we’ve tried several things. A perfect example of times when it is beneficial for a baby not to be held is tummy time. It is good for babies to have tummy time on the floor every day, rather than spend all of their time in someone’s arms. Tummy time helps strengthen muscles and helps babies learn about the world around them.
When it comes to letting your baby “cry it out” at naptime or bedtime, I don’t believe that it is detrimental as the author has stated in the article. As a baby gets older, they do learn to self-soothe, and it is okay to put them to bed awake so they can fall asleep on their own. Usually, within a week of enforcing the “cry it out” method, a baby will have figured it out and be able to go to sleep without crying.
I believe that if you are meeting your baby’s needs throughout the day, and are just letting him “cry it out” at bedtime, it will not cause the baby to distrust you. On the other hand, if a parent is repeatedly not meeting her baby’s needs, then, yes, it will have a detrimental affect on the baby.
Falling asleep on one’s own is something one needs to do throughout his life and is a skill that needs to be learned at some point. The “crying it out” method is not for everyone though. It is very hard to listen to your baby cry for a long period of time, and if you choose to implement this method, it is very important that both parents are in agreement and are supportive of each other.
