Settle a debate between DP and I.

At what age are they not classed as toddlers any more? So how old do they have to be?

Until they start preschool roughly... When it's no longer toddler groups, nappies etc.

In developmental psychology we group the ages together slightly differently. For example: Infancy; 0-2 years, Toddlerhood; 2-5 years, Childhood; 5-11 years, Adolescence; 12-18 years.
