Hello and thank you for writing to our JustAsk column,
I believe your question is to explain developmental learning. This means that children learn in the natural order of age progression. For example, a baby needs to learn to sit before they can crawl and then usually crawl before they can walk. This is a developmental process and in turn leads to learning / skill acquisition.
Hope this answer helps you. Great authors to read about developmental learning is T.Berry Brazleton and Brenda Nixon. T. Berry Brazleton gives a great explanation on how children learn new skills. "The Birth to Five Book" by Brenda Nixon also helps parents understand their children's emotional, physical, cognitive and motor development.
Thanks again for writing!
