Following on from the @EngMediaCentre child language course on Tuesday, here are a few links that I mentioned or resources that you might find helpful.
The Language 0-5 project have been busy recording and analysing all sorts of data and their preliminary observations can be found here: http://www.lucid.ac.uk/what-we-do/research/language-0-5-project/
The Liverpool Language Lab is part fo the project and you can see what they have been doing here: http://www.language05.co.uk/
Their posters are also very nice!

The @YorkToolkit site is great for all sorts of Eng Lang material, but for child lang, you can find a very good study by @cathelaing24 on onomatopoeia and infant-directed speech here: https://englishlanguagetoolkit.york.ac.uk/case-studies/onomatopoeia
We talked to Catherine on this episode of @LexisPodcast too: https://anchor.fm/lexispodcast/episodes/Episode-11---Catherine-Laing-el6r0m/a-a3io23k
