|Your Child At 4-5 Years Old (48-60 Months)
Your four year old has entered his fifth year of life and this is a time of huge social development for your child. Now officially a preschooler, your four year old may bud into an imaginative, talkative and energetic being.
By the end of the fifth year, your preschooler should weigh in at about 27-50 pounds and measure about 37-46 inches in height.
Four year olds enjoy playing make believe and trying new things. They gain a lot of self confidence during this fifth year as they take risks and are proud when they accomplish new things.
Although all preschoolers develop at their own pace, your four year old should hit some general developmental milestones by the end of his fifth year of life.
