Easy Way to Learn Child Develeopmental Milestones
Thanks to the American Academy of Pediatrics for this content.
Every child is different, and so is every parent's experience; but experts have a clear idea about the range of normal development from birth to age 5 — and signs that a child might have a developmental delay. Below you'll find milestones organized by period of development, and tips on when to contact a health professional about your concerns. Remember — there is no penalty for being cautious about your growing child, and if there is a problem acting early can make all the difference.
