Do you force your baby to sleep or just let him stay awake if he wants to? My 6-month-old is really playful and I'm getting bothered with his sleeping habit. He gets max of 2 hrs nap during daytime and 10 hrs sleep during nighttime. Should I be worried?

I don't think you need to be worried. If anything you're in an advantageous position because you've established consistency with your child's sleep habits. It seems like your baby is getting an appropriate amount of sleep at night so, i wouldn't be too worried.
