Why do babies wake up so often and so easily? Why do they seem to sleep longer/more profoundly when mommy is lying beside them?
If infants do wake up easily, then it’s likely biologically appropriate and dependent on method of feeding and general comfort level (condition of diaper and/or satiation-hunger status). Recall that breastfed infants wake up much more frequently and at shorter intervals than do bottle fed infants since cows milk is designed for cow brain growth (much less volume compared with human brains) and body growth rates while breast milk has just the right composition which means fast burning sugars and much less protein and fat for that ever-growing human infant brain which triples in size in the first year. All human beings including infants have their own unique sleep personalities and no two human infants (adults or infants) are the same. Mostly infants wake up because it is in their best interest to do so as their neurobiology is not designed for sustained, deep and consolidated sleep at young ages, before six months of age. They appear not to wake up as much next to their mothers but actu
