The IDRA link is great. It has all the 'must do' things in a structured way. I try to do them all but parents around me think I am too involved in my children's life, school and learning. I try to provide lots of home enrichments which are viewed as pressurizing children. Not that I care, but women like me are labelled as 'tiger moms'.

Comparison: Hart-Risley (lasting impact) VS HeadStartprogram (short-term effect)
This is an interesting thread. My DD3 goes to half day preschool 5 times a week. I do not see her doing any breakthrough learning, but her vocabulary, fluency and social aspects have improved a lot.

Early literacy related links and pdfs are excellent resources. Many thanks.
