At around 4 months, sleep can change FAST - and for a lot of parents it feels like it’s come completely out of nowhere.
Catnaps start. Wakes can suddenly happen every couple of hours. Settles and resettles get harder. Bedtime gets messy. Feeds become distracted. Your baby is suddenly looking at EVERYTHING. And then the drooling starts and everyone assumes teeth are on the way 😂
But there is a huge amount happening around this age, and most of it is completely normal.
Sleep cycles are maturing, sleep needs are dropping significantly, babies are becoming far more aware of their environment, and they can suddenly tolerate much more awake time than they could only a few weeks earlier.
Which is exactly why 4 months is such a good time to start looking at your sleep foundations.
Your routine. Your sleep environment. Your feeding pattern. Your settling approach. Making sure what you’re doing actually matches where your baby is developmentally now.
