Developmental Milestones

Developmental Milestones: 12-24 Months

During the toddler years, development milestones will vary widely from child to child. Unless your toddler lags in several areas or is more than a few months behind in any one area, there is little need for concern. Also remember that premature babies may reach milestones slightly later than a child who is born full-term, and that by age two, they will even out developmentally.
