My daughter was born in Dec and I decided to let her become a "Big B". Now that I look back I cannot be more happy with my decision, as she is clearly way ahead of some of the smaller kids in her class, and her grades are very good.
The way I see it - this is really an advantage only available to kids born between Sept-Dec, so why take it away from them?
it really depends on your child, There is some girl who was born in Dec but could still get into sacred heart kindergarten,true light kindergarten or st.paul church kindergarten.
