Baby's movements do tend to get into a pattern the further into pregnancy you get. My baby has had a pretty set schedule for a few weeks already, I made a note of times of day when baby VERY active for a while and, not just a few kicks here or there. The time baby becomes active can vary, but it will generally be like sometime mid-morning, or mid-afternoon, or middle of the night.
For example, here's what I've noticed from my baby(A day in the life of baby hehe): I literally have little to no movement from baby through the entire night. Usually if I get kicked, it's because my other kids have woken and are talking to me, or there's a storm. Thunder wakes this baby instantly. Throughout the day baby is very sporadic with kicks other than the set times I have noticed. I will notice kicks mostly when I eat, when there is music playing, or when I am poking at my belly trying to encourage kicks. Usually these kicks are just a few and then baby is done. However after I wake in the morning and have gotten up and about for a while, around 9 am(give or take a half hour) I have noticed that baby is almost ALWAYS kicking or moving about. The kicks aren't always the same, sometimes they're rough and painful, other times it's more just baby squirming around and bumping at my belly. The next time I get pummeled is usually around 2 pm, and then again around 10 pm. Again these times sometimes vary by 30 minutes, but they're always around these times. Monday I had a super busy day, and never noticed a single kick from baby. I realized it when I laid down in bed at the end of the day, about 9:30 pm. So I pulled out my doppler afraid something might be wrong, but heartbeat was strong. And 15 minutes later I was greeted with the hardest kicks ever. I just hadn't paid attention, and if the kicks are not real big that day they're easy to miss. The intensity of the kicks I don't think are what matters quite as much as that there is plenty of movements going on. Some kicks are just easier to miss, especially when you're busy. If you're not sure baby has a schedule, just try noting times of day when you notice baby is pretty active. Do it for a week and you'll probably notice a pattern. Times won't always be exact, but they probably will be close.
Hope this helps some.
