Have a look at this FAQ on how to start an EASY routine. It contains a link to sample routines.
Starting EASY - all you need to know and more!Do be aware though that at this age most LOs are only awake long enough for a feed, a cuddle and a nappy change. And sleep is often unpredictable, especially when they want to cluster feed in the evening.
At this age I really wouldn't worry about the soother becoming a prop too much. You can always wean it when it happens. Soothers are actually recommended to reduce the risk if SIDS for the first 6 months if it makes you feel any better
I would just offer the soother when you put her down to sleep and then shh part if you need to. If she sucks on it and then spits it out don't replace it unless she cries for it. That should help lessen the chance of it becoming a prop.
I never offered DS1 a soother but DS2 was self selling in the Moses basket with it from 3wo and just stopped wanting it at 7mo.
