The parents of a 5-month-old infant and a 3-year-old child ask the nurse about the sequence and timing of developmental milestones for the infant. Which is the most appropriate response?

1. “This infant should reach the milestones at the same time as your older child.”

2. “The infant may reach the milestones in a different order than your older child.”

 3. “The sequence of reaching each milestone should follow the same pattern but may be at a different rate.”

4. “There are no predictable patterns. Try to enjoy the uniqueness of each child.”
