I think that learning starts from the womb

but school should start when the children are ready emotionally and intellectually. This is because from my experience, I was qualified & wanted to go to school (kindergarten) at 4 years old but when I was already in school, I did not want to attend anymore because I realized now that I'm a mom that I was not emotionally ready - I was a shy, geeky child, did not know how to socialize and was happier when I learned new things than meeting new people.
That is why I am thankful that there are playgroups where my child can socialize with other children and libraries and bookstores that have activities for young children (since we had to take him out of daycare when he got sick).
