Baby Temperament and Sleep Series: Part 1

Baby Sleep & Temperament Article Series

This is Part 1 of my Baby Temperament and Sleep Series. This series is about your baby’s temperament and how it might affect his sleep and/or how you solve sleep problems.

Across this website, I mention temperament a lot and how it DOES affect what sleep training method you might choose to help him sleep better. His temperament and personality will drive whether a no-cry method will take 1 hour or 3 months or, if you choose a cry-method, whether he will cry for 5 minutes or 2 hours, if you let him. It may also affect how difficult it is to wean him from breastfeeding, wean him from the bottle to a cup, how many errands you can run on a Saturday, how many tantrums he has as a toddler, and many many other things parents face on a daily basis. Just a reminder, I am not a doctor, so this is based on my reading / research about Temperament and how I believe it affects your baby’s sleep and what methods may or may not work well when it comes to sleep training. Remember sleep training is not cry-it-out! Let’s get started!

What Is Temperament?

I happened to get my definition of temperament from the book, Raising Your Spirited Child. The author uses the terms coined by Drs. Stella Chase and Alexander Thomas, “because of their positive, parent-friendly approach”. Even if your child is not spirited, the temperament traits will apply to all babies. At the end of this series, I will give you a quiz to find out whether your child is spirited or not and what his or her temperament is.

Temperament is how your child naturally reacts to situations and stimuli, her mood, her ability to calm herself and how active she is. It is said that researchers have found that temperament is biological, meaning your child comes out of the womb this way. This means that from day 1, the way a YOUR baby reacts to being wet, hungry, tired, etc. may not be like your friend’s baby. Yours might be low-key and not get very upset or your baby may scream loudly. You are not making it up that your baby might not be “laid back”. You might wonder what you did or didn’t do to cause this. I remember one parent saying her husband thought her post partum depression after the birth of their son caused their baby to not sleep well. What a burden to bear! Let me assure you, I did not have post partum depression, was not depressed during pregnancy, or anything close to that and my son had a lot of sleep problems! You have no control over your baby’s temperament. You can only “blame” your genetics and they are still figuring out how it is all intertwined.

One thing that is important for you to know, though, is that you can get to know your child’s temperament and be able to predict how he will react to certain things and you can set him up for success. If you know your child has trouble with transitions, for example, you will be able to help him with those (I will get more into that throughout the series). The best part of this is that you can reduce some of the stress once you KNOW your child’s temperament because you won’t constantly be trying to figure out why he is reacting a certain way. Most of all, you should know that just because he is born this way does not mean that what you do does not matter. You will be able to emphasize his strengths, help him understand his own temperament, and help him learn how to handle his own reactions as he grows up. As Raising Your Spirited Child states, “By adapting your parenting techniques to fit his temperament and his style, and teaching him the skills he needs, you help him to live cooperatively with others and to be all that he can be.” To attempt to make him ignore his temperamental traits is not only very difficult, it teaches him to not be himself.

In the next 10 parts of the series, I will review each of the 9 traits of temperament, Intensity, Persistence, Sensitivity, Perceptiveness, Adaptability, Regularity, Energy, First Reaction, and Mood, discussing baby sleep along the way and in the final part, take an assessment quiz to help figure out you and your baby or toddler’s temperament and see how it might be similar or different.

    I really appreciate this series, I’m enjoying reading all the different traits of temperament! Right now I’m going through an awful sleep time with my 11-week old son, and it’s interesting to try to figure-out his temperament and compare it with my 2 year-old daughter’s who was also a horrible sleeper at this age. I get so frustrated when people take a one-size-fits-all approach and simple things seem to work for their easy babies and it seems like I must be doing something wrong because those things don’t work for my difficult babies. (I mean “spirited!”) It doesn’t make me any less tired, but it is comforting to know that I’m not doing anything wrong, it’s just how they’re wired, and that’s ok.

    @Emily I feel the same way when people would give me simple things to try like I hadn’t already tried them. The worst was when people told me to keep my son up so he’d sleep better. Not!!! Very frustrating, so I’m glad you don’t feel as alone, now.

  3. Jennifer says

    This is a great site! I esp. appreciate the summaries of the different sleep training methods. I’m also glad to hear that I’m not the only one with a baby who refuses to learn from “crying-it-out”! I am a new mom with a 2 month old, and he has had trouble getting to sleep since he was born. Now I’m getting to know him better (Intense, Sensitive, Persistent boy!), but it was really rough at first and continues to be a new challenge everyday!

  4. says

    @Jennifer Typically, 2 months is too young for cry-it-out anyway as their ability to self-soothe is limited. No amount of crying will help any baby, regardless of temperament, if they do not yet have the ability to self-soothe so they really can’t learn how. Usually, it’s closer to 4 months old that this can work. It depends on the baby. At some point, you can work with your baby to help them learn how to fall asleep and at some point you will realize what they once NEEDED to fall asleep, now they simply WANT it and they do have the ability now. Thank you for commenting and I’m glad you’re enjoying the site! Good luck!

    My son is 13 months old and I just took that quiz for him and it says that he is spunky,but what of the 9 temperment trates does that fall under?

  6. says

    @Jessica If you take the quiz and enter your e-mail, it will give you all the questions and your answers. It really just depends on how you answered the questions and what makes him “spunky”.

    Hi Gina,
    Are you working on weaning your daughter from breastfeeding all together or just for night feedings? If it’s related to night feedings and wakings, you might want to read through this four post breastfeeding series which also talks about breastfeeding and night weaning. You can find all four posts here:

    If you are weaning completely, then you might want to do a search on this search for additional help and ideas for how to approach that:

    Breastfeeding is also a source of comfort for many babies and toddlers, so it might take some time for her to adjust. You might try limiting breastfeeds a little more each day or let her know that feeding with mommy will only be before naps or before bedtime so that she starts to get used to the idea of fewer feedings.
