My daughter 4 year does toilet in standing Position and do potty in diaper, she tells everytime about both but doesn't sit on pot, what to do

A. Potty Training can be started after the age of 2 yrs.for this you need to develop a conditionedvu reflex in the child by fixing a particular time regularly in which thve child should be sitted over the potty seat .do not force the child instead make it a playful activity and not to make the child repulsive about it.slowly the child will learn to indicate before the time.
