good intro but i dislike several factors. also note that i read the 7th edition and did not both paying more for the 8th.
the summary is that this is a good generalized textbook with accurate information to the field of FLA. however i felt like information in this and other resources are presented as givens with little room for variation, which is what occurs in reality. that is, not every child acquires specific milestones at the same age. these are averages and generalizations. it doesn't take into account children of other backgrounds, for example the social issues that may influence child first language (or simultaneous multi/bi lingual) aquisition. poverty, immigrants (from what cultures?), single parent households, different non-mainstream educational challenges were generally not presented. it spoke briefly about deaf and autistic acquisition points. additionally it did not cover that sequential bilingualism is actually L2, which doesn't mean too much in terms of the information. ONLY that there are a lot more variables in acquisition and i felt this textbook did not take such things into account as it should have. the audience is a generalized student population, and i have children so i know a thing or two about it. i am able to test out some of these 'givens' and offer exceptional evidence to some "given milestones" and it bothers me that "scientists" come into the field learning things which may or may not be true. fortunately i had an awesome teacher to accompany the text.
i do not have an alternative "better" or more appropriate text and i would suggest this still as an introduction, after acknowledging these points to the students of such a text. they might also learn that through an assignment where they are expected to collect data, and analyze it in a write up, an academic term paper with specific standards. (I took SLA theory first so this textbook was really light in comparison, and focused more on the stating information vice learning to collect info. I suggest for SLA/Data collection on FLA/SLA Ellis & Barkhuizen actually.)
