Okay so this has always perplexed me. It’s not so much a question of why babies need sleep. I understand why everyone needs sleep. Put simply, their bodies grow and repair themselves. However, I’ve been told by many parents that they put their babies to bed at 7:00PM and they are supposed to sleep until around 7:00AM. What I have found, however, is that most of the same parents also complain that their babies are waking up waaay too early. My roommates, specifically, have been dealing with their baby waking up at 4:30AM very consistently.
I have studied the mechanics of sleep (cycles, stages, conditions, etc) on account of my narcolepsy. The science doesn’t add up here, but I am certainly not a pediatrician. To compound the issue, they also put their babies down for naps that are often a couple hours long. Wouldn’t this be counter-intuitive? Babies should have a circadian rhythm, and their bodies should naturally know when they are ready to be awake. Is this really the correct course of action for a baby? Why do babies need so much sleep?
In: Biology
Babies don’t actually develop a circadian rhythm for the first few months. In general, growth and development takes a lot of energy and sleep conserves energy and is especially important for cognitive development, which babies are doing a lot of. The lack of circadian rhythm can exacerbate this, as they have shorter sleep cycles.
