Feeling 10 kicks in 2 hours is fine. Are you worried that baby is too active or not active enouch? There is really no such thing as too active. I am a labor doula, so I work with moms through late pregnancy all the time. What I have learned and tell my clients, at least as far as late pregnancy (like the last month) is that pay attention for an hour, if you get 10 movements, everything is great. If not, drink a glass of juice (orange preferably- the sugar wakes the baby up), relax, and focus on baby. continue counting from the last hour, and you should get the 10 by the end of the hour. The term kick count is really not a good term, because you are looking for any movement, even the slightest wiggle. Alot of moms tend to think that it has to be a definite kick. And like a lot of other people have already said, baby is usually sleeping when you are up and about, but wakes up as soons as you sit down for a little while or go to bed. I have never heard 10 kicks in 10 hours though.
From what you have said here, I would not be concerned.
