Baby bedtime routines

I’ve seen a few posts about this subject.

The things I’ve tried haven’t been working. So if you ladies wouldn’t mind, please share with us all your little one’s age and what your bedtime routine is. How many hours a night does your LO usually sleep? What age did you start the routine ?

And any other info you can share ! Do they nap a lot during the day? How long does each nap usually last ?

If you did some sort of sleep training method please share what that was ! A lot of new parents are struggling out here !

Thank you in advance
