Looking for some info/input/opinions on how you get bubs to sleep.

What is your bedtime routine?
What are your sleep triggers?
What time do you get your DD/DS to sleep?

At what age did you establish this routine??

When should I start trying to establish a routine with DD? She's only 5 weeks old... but DH and I are very keen to have a definitive bed time - like 6 or 7pm every day.

The antithesis of this is my 9 month old niece who goes to sleep any time between about 8 an 11pm...
