Hi queenbee, my DD is not much older than yours about 6 weeks or so. This is her bedtime routine, same for night as it is fer her day sleep.
She her dinner about 5-5.30, then play time with her big brother til about 6.45ish, then bath time again with her big brother, then we come downstairs and I give her sleepy time dummy, I get her bottle, we go back upstairs and she gets her bed time buddy (a furry bear) and she drinks her bottle snuggled up to me with the lights out on her rocking chair, I quietly sing her bed time song, and pop her into her cot awake but very snoozy, she rolls over and goes to sleep. Sometimes she fights it but I just pick her up rock her a bit and she calms down. She doesn't sleep through the night though and she does get 1 bottle overnight. Sometimes I'm up once sometimes 3 or 4 times. Most times (other than her bottle and nappy change) it's just a dummy replacement (damn thing!) so only takes a minute. Yes I'm pretty shattered from being up so many times at night but I can't let her cry as she wakes my DS and then its really on and they both scream!
I think the key is consistency and also telling her what is coming up next, like let her know it's play time and then tell her "in a few minutes we're going to have your bath", then tell her "it's time for your bedtime milk", and then when she's having her milk tell her "when you have drunk all your milk Mummy's going to read you some stories/sing some songs" and then just before the last song/book tell her "it's time for sleep". If all goes according to plan she will soon learn to associate the familiar routine and the same phrases with going to sleep. It worked for both mine and I don't usually have any trouble getting them to sleep, the problem lies with them staying asleep!

Good luck.
