Important Milestones: By The End Of 7 Months

At seven months old, infants respond to others' facial expressions, roll both ways, and babble. As an element of early intervention, Learn the Signs. Act Early. developed this fact sheet to help parents, teachers, and staff understand developmental cues and red flags for seven-month-old children.

The following fact sheet is provided courtesy of the Centers for Disease Control’s Learn the Signs. Act Early. Campaign.
