Your baby seems very normal. A lot of people experience a couple of weeks of sleep bliss with their newborns and then all of a sudden bub starts to wake more or sleep less or sleep all day and stay up all night (like mine did!!!)

Don't worry about bad sleep habits at this point your bub is still getting used to being outside, and they don't really know the difference between night and day either.

Personally I don't try and do sleep routines until my bubs are a bit older like 4 months. I do however start a flexible sleep association routine, for example swaddling, music, shutting curtains etc.

BTW: Just when you think you've got them into a good routine, etc they'll change!!!
