I personally started setting a routine for my little one as soon as possible. which for us was around 3 weeks old. everyone is different and different kids like and thrive on different routines!🤗 kids thrive on consistency!?
I focused less on a set routine and more on following baby's cues and doing things in the same order, so baby knew what to expect.
There is no such thing as too early when giving your newborn a routine. The sooner you start, the better.
As soon as you can. Figure out his wake times and start from there (when does he eat for example, when to go for a walk,etc) baby will look forward to it
