While I have been looking at ways of removing the unsuitable "Child Acquisition" stuff from English Phonology, I have come across the odd situation that WP has two articles covering almost the same ground, one called 'Language Acquisition' and the other 'Language Development'. Looking at the related Talk pages, it looks as if several people have proposed over the last few years that the two should be merged; I can't see any signs of opposition to the idea, but nothing has happened. I have queried this in both Talk pages, but I don't suppose I will get an answer.
