As soon as possible also... Same routine bath,lotion, ,bed... As they get older maybe add reading a book or watching a movie ... But stick to the same time every night as much as you can..
as soon as possible! bath lotion bed. they'll get used to it so quickly. I had my now 3 year old on a routine by 6 weeks. only waking up around 2-3am then 6:30am. it was heaven.
I'm trying to start him on a routine and he was in bed by 8 but his father won't follow it so when I'm at work it's going to get screwed up
