Infant Development: Alignment, Core, and Motor (IDACM) – 101: Typical Assessment at 1, 2, 3, and 4 Months of Age


This online course is meant to help early intervention specialists gain a deeper understanding of typical motor development at 1, 2, 3, and 4 months of age. In each age, you will see an infant examined in 5 different positions. In each position, we will highlight the typical expectations for baby in relation to specific areas of the body: head, trunk, upper extremities, and lower extremities. The importance of placing baby in each position and the goals of development in that position will also be explained. Additionally, the self-paced course will give you information to help guide you through your sessions, questions to ask, and tips on how to get the caregiver involved.


Course Objectives:

  • Learn typical motor development at 1, 2, 3, and 4 months of age

Hugely added to my knowledge base. Content was structured well.

It is very detailed. The videos are a great visual and allow the participant to really understand the movements and what is being targeted during the modules.

The presentation style and the positioning of different stages beside each other to compare and contrast. Also like the use of a real baby vs doll/pictures to illustrate what was happening.

I really like this course. As a functional therapist for children, to a large extent, I can see the details of the development of typical children from more angles. Thank you!
