It all starts with tummy time! Baby milestones fall into three stages:
Primitive Stage- Birth to 3 months
Transitional Stage- 4-9 months
Mature Stage- 10-12 months
🍼The Primitive Stage is that time right after birth and lasts up to around the three month mark. During this stage we’ll see the baby interact visually with the world around them. They watch, listen, and make basic movements.
🍼The Transitional Stage is that period of time around 4 months to 9 months of age. We’ll see greater development of things like grasp and controlled movements, effort, interaction with the world around them, and intentional movements.
🍼The Mature Stage occurs around 10 to 12 months. During this period, baby freely moves their body to manipulate items in their world. They improve and refine mobility, grasp, and communication.
Each stage of baby development has their own hallmark milestones.
Typical development follows a pattern in child development. Progression through developmental milestones typically occurs in areas of fine motor skills, gross motor skills, the senses, cognitive development, and social development.
🍼Use these play activities as development-based activities to guide and foster play.
