Have you experienced putting back toys being thrown by your 15-month old child from the playpen or the high chair again and again? Tired of figuring out why they have to cry so hard when you stop, leading you to either giving in or dying of guilt? Ever got freaked out seeing your two-year-old ruin your make up set, or attempting to use his or her father's electric razor? Has it ever been concerned you when you noticed that your child has been imitating your actions, that you have become cautious of what he or she sees in the house and on television? Toddlers are children within the age range of 13 to 36 months. They are considered most misunderstood at this stage, as this is their period of transition from infancy - a stage of total dependence, to pre-school - a phase where they tend to be much more explorative in life.
