Interesting question. In fact, it is fascinating to see language development happening “live”. I’m now even more interested in the topic and because my son is bilingual I’m more and more interested in bilingualism. I have been recording my son’s language development. It is also quite interesting to contrast the theory with the practice and understand some of the challenges that parents coming to the lab face every day and that we simply cannot see as researchers. But as you can imagine, running after a toddler 24/7 is an amazing but exhausting job!
