What we did (right from day one) was decide on a bed time (7:30 in our case so that Daddy gets a bit of time with her after work), and set that as bed time. The bedtime routine starts just after 7, when we take her to her room, close the curtains, strip her off, so she gets some nappy off time, and normally plays with Daddy, while I run her bath, empty the nappy bin, get her night time clothes etc together. We then share bathing her (alternate nightly), after her bath, I dry her, put her nappy on and sleep suit. I then turn the main light off, and give her a breast feed. When she is finished, I lay her in her cot and put her in her gro-bag, say good night, turn the lamp of and close the door. I don't talk to her after I start giving her her feed, and from then on I treat it as "night time" I don't talk to her or stimulate her at all, and I won't take her out of her room. If I need to go back in and her her a hug, feed, nappy change lie with her etc I do so but I don't turn the light on, or talk to her. I then get her up at 7:30am, every morning.
What are you day time naps like? Then she was sleeping for about 3hrs spread throughout 3-4naps.
