This article describes the Montessori environment that can be provided to children from 1-2 years of age. It includes topics like Montessori toys and materials appropriate for that age group, Language development and the 3 period lesson.
A detailed child development guide from birth to 19 years is available at this site: http://www.dshs.wa.gov/ca/fosterparents/training/chidev/cd06.htm The child development guide includes the physical, intellectual, social, emotional and moral characteristics that are normal for a given age. I found this resource extremely helpful to get a bigger picture of child development stages and what to expect at each stage.
The common concern of most parents is whether their child is reaching development milestones or not.
This site (http://solutionsnottalk.com/developmental-tasks/) provides a summary of all the developmental tasks from birth to 19 years listed by age. My son is in the 7-9 month range now. These are the developmental tasks listed for that age.
7 – 9 Months
• Sits without support • Crawls • Emotional attachment to parents • Separation anxiety • Distinguishes between living and non-living objects • Aware that objects exist even when out of sight (object permanence)
