Hi Veronica,
Here is a good resource about attachement.
The Best Start Resource Centre is pleased to offer a booklet on parent-child attachment. It is called My Child and I – Attachment for Life. This resource is for parents of children aged 0-3 to help them understand the principles of attachment and learn ways to promote attachment with their young child. Simple activities are suggested for each age group. The booklet contains additional information on childcare, adoption, separation and divorce as well as discipline. This resource is already available in French. You can download and order the booklet at http://www.beststart.org/resources/hlthy_chld_dev/index.html.
If you download the PDF it's free, but if you want a hard copy you have to purchase it.
