In the UK children do start schooling at an early age of 5 . In India it is a lot worse. Children start formal education at the tender age of 3.
Overwhelming evidence elsewhere has showed the benefit of joining school, as late as 7 years. For example in, Finland and Sweden children reap the benefits of joining school late. These children perform academically better and their health and emotional well being are much better than those who started much earlier.
On the other hand problems such as stress and other mental health problems are much more common in children who start their schools early.
In our country we do not have a choice but to let our children start at the completion of 5 years. But we could avoid sending them earlier…….
