Good question... it's great that you're putting in so much thought about your child's daily activities! Studies have shown that babies who are ten months of age need at least 14-15 hours of sleep every day. You'll find it hard to keep your kid tucked up for so long, though, as you kid will always find a way to escape but you can try and get your kid to sleep for 12 hours at least. Make sure that your ten month old baby sleeps during night time, as this is the most peaceful time when noises will be at an all time low.
