Information about breastfeeding after 1 month of postnatal life, maternal age at the time of evaluation, academic level of the parents, single-parent family habits, and postnatal readmissions within the first year of life was gathered.

There are 21 versions, adequate for each age, from 2 to 60 months. Each includes the five domains of development: communication, fine and gross motor skills, problem resolution, and sociability. In each section, six questions are raised about child performance, the answers to which were: “yes, he usually does that (10 points),” “only sometimes (5 points),” or “not yet” (0 points). The result is obtained by adding each domain and the global score. Furthermore, there are nine questions for the parents to answer directly and subjectively about some development and behavioural traits of their child. The total and partial scores are compared to the cut-off points determined by the ROC method, classifying the result as optimal, intermediate or low for the age, the latter being the average-2 SD.
