7 Reasons Babies Need Sleep

general Jul 15, 2021

    I'm sure you’ve heard that babies sleep a LOT.  Or is it that they need a lot of sleep?  I found myself questioning this as a first-time mom and didn’t think twice about the amount of sleep my newborn was getting until my pediatrician asked me.  I assumed that she would sleep however much she needed.  I thought the fact that she was fussy every day between the hours of 6 pm and 8 pm was "totally normal."  I think I remember being told it was “just a little colic.”  A whole new world of knowledge opened up to me when I realized my newborn needed 18 hours of sleep, and the American Academy of Pediatrics actually sets guidelines for babies of all ages. Sleep is a crucial factor to a child’s development, and even more so in babies and young children.  But why?

  A new study presented by the 2019 American Academy of Pediatrics revealed that up to 50% of children up to the age of 12 are not getting the recommended amount of sleep. 


Here are the top 7 most interesting facts on why babies need sleep:

1. Memory Consolidation:

Sleep is when memory consolidation occurs.  What does that mean?  As your child learns new skills as a baby, it is during sleep that he can sensory process and actually master the skill.  Think of it as a mental workout.


2. Growth Hormones:

Lack of sleep inhibits growth hormones and can cause a deficiency.


3. Metabolism:

Lack of sleep also affects the ability to metabolize food and impacts the production of leptin hormones which tell a child they have had enough to eat and can, long term, lead to obesity.


4. Better Behavior & Learning:

Sleep improves attention, behavior, and learning.


5. Protection and Safety:

Sleep protects children from vascular damage that stress hormones can cause.  "Children with sleep disorders have excessive brain arousal during sleep, which can trigger the fight-or-flight response hundreds of times each night," says Jeffrey Durmer, M.D., Ph.D., a sleep specialist, and researcher in Atlanta. "Their blood glucose and cortisol remain elevated at night. Both are linked to higher levels of diabetes, obesity, and even heart disease."


6. Immunity:

Sleep helps build the immune system and produces cytokines, a protein our bodies use to fight sickness.  


7. Focus & Emotional Regulation:

Sleep promotes focus and emotional regulation.  Children with less than 10 hours of sleep under 3 years old were 3 times as likely to have hyperactivity issues as found in a Sleep Med Study in 2015.
