I heard I think Lucy call it a rhythm & thats what we go with. Around a certain time of the day certain things may happen... and thats what we do. For Matilda she thrives on strict routine so before bed we have an order of the way we do things, but we always follow the rhythm of whats going on. So if she's not tired at 7pm we wait and read some more stories and have quiet play with her... etc (she's 2 1/2). With Jovie who has just turned 6 weeks, its all on demand, she's tired and we put her to bed. She's hungry & I feed her....
