They may not keep you awake at night ever. I'm 31 weeks and most of what I feel are rolls. No kicks or punches. It certainly doesn't keep me awake, but everyone is different.

I'll be interested to hear whether or not the pattern thing is accurate for you.
I've had five babies, and other than their super active time being relatively consistent, nothing has carried over. I think because before they are born they do their own thing, but afterwards we change their environment. Like today, baby dd would have slept this morning, but we were running errands and had her in and out of the car. So, this afternoon she was cranky from being over tired. Now she is sleeping hard, but that will probably mean she'll be messed up tonight. A few days of that, then whatever they did before they were born is moot.
