depends on what kinda sport.. i'll ensure they take extra precaution like example helmets and padding if they're doing sports like cycling/skating

not really but depends on what kind of sport. As it is really important for kids to exercise in any form

children running around & being energetic = easier to put them to sleep

Sports could be as early as possible...builds motor reflexes

Not at all! It's a good habit to cultivate early in life.

I started playing tennis at 3 so shouldn’t be an issue

Younger the better to encourage a healthy lifestyle

Nothing to vigorous. Maybe playing with kid scooter

I always have sports dates with my 18 month old

No, its good exercise. Just dont too tiring
