she needs to learn to get to sleep on her own.
With both of mine I had the same bedtime routine - dinner, play, bath, story, bed and both had dummies till 2yrs but...
With DS1, I would feed him, then very gently nudge him awake as I put him down in the cot, then walk out the room.
If he didnt settle, I kinda did the CC thing. I always let him cry for a bit before going in to him. I waited till his cry changed (you know yourself when they are just having a tired winge or are distressed) a couple of mins max, then went in, put hands on chest and "shushed" him. Repeated as often as required. This was usually enough and I very rarely picked him up to settle. I only picked him up if unwell/teething and crying persisted longer than normal.
DS1 has always been a fab sleeper because we were consistant with above method. (or just that we were consistant)
With DS2 I was unable to leave him cry incase he woke up DS1 or DH so I always picked him up the minute he made a noise. I also fed him to sleep & put him down asleep.
As a result it has taken to now - 2 1/2yrs for DS2 to sleep through the night without me having to go in to him. For ages he needed milk if he woke up as his sleep association was me feeding him to sleep. Then I cut out the milk at night and he wanted cuddling/stoking to sleep. (that started when he had croop) Now I do the supernanny thing of not talking to him & just put him back into bed and walk out the room. This has finally cracked it!!
I so wish we/I were as strict & consistant with DS2 as we were with DS1!
With the Dummy business, I would say the earlier you remove the dummy the better. I waited till mine were old enough to be bribed (they left their dummies out for the dummy fairy in return for a toy) around 2 yrs but that meant many occasions of having to crawl around on hands & knees in the dark looking for lost dummies. Many of my friends got rid of dummies around the 4-6 month mark & I wish I had been strong enough to have done it then too!
I would also say to introduce any changes to sleep routines at nap times. That way if it doesn't quite work out as hoped, you are not missing out on your sleep and there will still be other oppourtunities during the day.
