"I just finished reading your book and I have loved it! I wish I had gotten it when my baby was born. It confirmed what I had always thought about my babies’ sleep, but everyone always made me feel bad for putting my babies to bed so quickly and not keeping them up longer. I listened to the others and ended up with problems. I got your book when my little guy had just turned 6 months old. I have read it thoroughly. My problem is trying to start out cold turkey at 6 months. I’m having a hard time figuring out when to put him down after 90 minutes or when he is ready for longer awake times. I try to watch him for cues, but he has been such an erratic little guy since he was born, that he’s hard to read. I was wondering if you had any general advice for getting started at 6 months."

It sounds like the book affirmed what you suspected all along. I'm glad about that

I think if I were you, I wouldn't be doing anything differently from what it sounds like you're doing: looking for signs of sleepiness, and responding asap by providing an opportunity to sleep.

Be guided by your observations. See which sleep opportunities at 90 minutes were followed by sleep and which ones weren't.

My guess is it will take a few days or a week or so to sort it all out.

As a broad guideline, many (but not all) six-month-olds have a 3-hour stretch in the morning once they're up for the day, and another before they go down for the night.

There might be other 3-hr stretches in between his daytime naps. You might not see this yet if he hasn't been getting his full allotment of sleep for some time.

Once your little guy starts getting more regular naps and hopefully longer naps, you'll know which are the real alertness intervals to follow up with a nap.

Make sense?

If it doesn't, can you try to describe for me what cues you're going by? That might help me be more specific.
