H.1.
Not to be oppositional here to the other responders, but there really is no need to push his bedtime later. That is a perfectly acceptable bedtime for his age and its a common misconception that keeping babies (or children) up later makes them sleep better or later in the morning. So not true! I think your routine sounds fabulous, why change what's not broken? Sounds to me (though I haven't read your previous post) that the night time waking and wanting to play should be handled by other means (ignoring, likely!) Please read the book Healthy Sleep Habits, Happy Child - it has been a life saver!
To more specifically answer your questions though - we have a 15 month old son. Around 6:30 or 6:45 we start our routine, which is really pretty short. If its a bath night, we do that first. Then to bedroom which we have very mellow with his fan on that he sleeps with, lights down, etc. We put on pajamas and then Henry has a sippy cup of water while we look at a couple of books. Then we sing our goodnight song and give mommy and daddy kisses. Then, put him in the crib and leave! I think the only difference when he was around your son's age was we did a bottle right before singing the goodnight song and putting him in his crib.
Good luck to you!
