Getting LO to sleep

Laura
So my daughter sleeps through the night, from 8pm-6:30am, and she is an ok napper but we have the hardest time getting her to sleep. We have to rock her for at least ten minutes but it's often closer to twenty before we can put her down. And this is after she has had her last bottle and is clearly tired but not overtired. Does anyone else have to run a marathon to get their kid to sleep?
