I used to think of sending my boy to N1 when he's 2 yrs old next yr (now he's 1 yr old). Like the above moms, he may learn discipline in his schoollife.
Now i think of not sending him to N1 coz I'm a full-time mama & not as in need to send him to N1 as working mama. I agreee w/ the above mama that if only grandparents or maid taking care of the bb, it's better to send him to N1. I think i'll send him to playgroup instead (coz I can stay w/ him during playgroup time)!
