hi emma,
i have just done this question...
i used a book called child development 2nd edition by carolyn meggitt.
it has child development up to age 16, it contains physical, social-emotional and commuincation. it did take me ages to do it though but i think i was trying to research too many books at the same time.
in physical i also refered to puberity aswell - oo, scary!!
i have only just started my level 4 and yet to show my work to my assessor so i feel a bit out on a limb, if you know what i mean!!
there is a thread on this site were someone has recommened a list of books, i search my local library for most of them and bought a few. you'll have to do a search.
not sure if that helps any?
