when does a toddler become a child?

[Flossish]

DS is nearly 4 and isn't a toddler really. Although sometimes I look at him toddling along and he does still seem like one IYSWIM. At what age does a toddler become a child IYO?

Some time between 3 and 5 IMO.

so ds is half way out of being a toddler! anyone else?

dd stopped at about 3. and at 4.5 her legs have suddenly entered small foal territory.
