i think is ok to start early . . as kids can explore and learn new thing from school and also be more independent and sociable.
Is good to let him go for 2 hours session, he can mix around with other children and learn independent.
My elder started at 2yrs old , it's good to let them start early so they can adapt
No too early .can let him enter 2years old.i also bring my son at 2 years old
it good to start early they can explore n learn to be sociable
its gd to send them early to socialise with other kids!
My older 2 kids started at 18 months
