At the risk of being immodest, you could read this, a few years old:  
http://www.internationalbreastfeedingjournal.com/content/1/1/29 

Feeding by numbers: an ethnographic study of how breastfeeding women 
understand their babies' weight charts
Magda Sachs , Fiona Dykes and Bernie Carter 

Depending what you are interested in, the references will lead you to other 
places. 

A really interesting international paper is:
Trop Med Int Health. 2007 Sep;12(9):1074-86.
Plot and see! Maternal comprehension of growth charts worldwide. Roberfroid 
D, Pelto GH, Kolsteren P. 

Hope this helps.
