                                            Here’s the tea on wake windows!
It can be helpful to know how long your baby/toddler can comfortably stay awake before needing to nap/bedtime (sometimes referred to as a wake window).
The reason it can be helpful is babies find it easier to fall asleep quickly and happily if they’re tired enough. So whilst “wake windows” aren’t really scientifically based, the biological drive to sleep is very much so! 
Sleep drive, or pressure is that feeling you can’t fight when you’re trying to stay awake and watch something good on the TV, but your eyes keep closing and your body says no! Sleep! 
It’s actually a build up in the brain of a chemical called adenosine, whilst you’re awake, and then gradually dissipates whilst you sleep. 
Often babies need the shorter end of how long they can comfortably stay awake for in the morning, before their first nap, gradually needing longer awake before subsequent naps/before bedtime. 
And just to say, some babies do something different from the charts. And that really is ok. Some days can be very different. 
Try not to worry about things you can’t control and how long your baby does or doesn’t stay awake for is often out of your control. 
Does your baby roughly follow these wake windows or do they do something wildly different? 
Oh and p.s, I’ve left out baby’s first month as it varies so much, literally no point in trying to cover the variation in a chart!
