Some people believe that children should be allomunicate very early because of this. They are generally more confident and independent than children who stay at home with their parents and who are not used to strangers or new situations. Such children find their first day at school at the age of six very frightening and this may have a negative effect on how they learn.
Another advantage of going to school at an early age is that children develop faster socially. They make friends and learn how to get on with other children of a similar age. This is often not possible at home because they are the only child, or because their brothers or sisters are older or younger.
So overall, I believe that, attending school from a young age is good for most children. They still spend plenty of time at home with their parents, so they can benefit from both environments.
