Critically think about the developmental stages of infancy through toddlerhood. Familiarize yourself with Module 3’s objectives, introduction, video, and articles. Use the articles in Module 3 as your primary reference, then use the Saint Leo Online Library for peer review sources and to find relevance to this week’s topic.

Questions:

1. As an infant develops into toddlerhood it goes through many mental, emotional, physiological, and psychosocial changes. List one biological, cognitive, and psychosocial change that is significant to this development, why?

2. After familiarizing with Module 3’s video and articles, consider Piaget’s Cognitive Theory of Development. What does this theory consist of: how many stages, what do the stages entail, are there any weaknesses?
