Self soothing

Essentially, you can't lovely. Until the age of 3 they don't have all the parts of their brain to be able to. They need to be shown and supported until then if their temperament means they need it. Babes that can until then have the temperament to be able to and some then learn their needs aren't being met if left to their own devices (pretty much all sleep training does for example). They need to borrow us for our skills to show them. Then as they grow like us they do learn what they need to do, roll over, grab a blanket, get a drink, go for a wee etc etc. The vast majority of adults don't sleep through the night, we just know what to do and have all areas of our brain so that we respond quickly and often don't even notice.

Chances are if its a new thing, its down to devlopment, teething, illness, any changes and will go back to how they were before once through it. Layering comforts can help do it more quickly but all depends what it is they like too again often down to temperament xx
