I was very fortunate that from around 5 weeks, my LG began to sleep through the night. She went on to be formula fed and now everytime she has a warm bottle, associates it with "sleepy time" and goes for a nap, so when she shows signs of being tired or needing a nap, I give her a bottle.
Over the past 3 - 4 weeks though she has been a bit difficult to get down so around 8 or 9pm, I will run a bath for her and bathe her infront of the coal fire. Once she has had a bath, she gets a 5 minute massage with baby lotion which she loves (giggles everytime!), gets into cosy pyjamas and my partner will have got her a warm milk ready for me to sit down and feed her.... she doesnt seem to finish the bottle before being sound asleep and thats her for the night. Although she didnt have a problem sleeping through, she was getting difficult to put down and I find that sticking to the same routine around the same time every night really works. She is in the bath for a good 20 minutes kicking about, splashing, giggling and tiring herself out so it really helps, plus its warm and relaxing for her.
We live in quite a big house so I put her in her moses basket after falling asleep on me for approx 20 minutes to ensure she is in a deep enough sleep in the room next door (joined to living room) with the lights off and the door ajar so i can hear her if she stirs. Once its time for us to go upstairs to bed, I trasnfer her from the moses basket into her sleeping bag and into the cot and she sleeps great. Even if she wakes up briefly when being trasnferred, she goes to sleep as soon as the light is out on her own accord, sometimes she will need a dummy to soothe her.
I think the moses basket is a comfort thing for her, her fleecy blanket, the warm milk and the relaxing, fun bath before bed with the routine being the same every night has really made this work.
I used to take her a walk and she would fall asleep but the difficulty was getting her out her snowsuit and into the moses basket without her waking up (rarely worked!)
