potty training?? like off diapers? u have to start frm home first...depends on the child readiness..never never rush the kid..i think 3 yrs old is a good age to consider..n this is also different frm child to child..once u start and thrs some progress, den slowly liaise with the class teacher.
we started when the LO was approaching 3, he started to show signs that he was keen to use potty so we got him one. his daycare teachers informed they are starting potty training later half of the year, when most of the nursery kids turn 3 ☺
