Why do babies say "daddy" earlier and what might it mean when a baby does call for "mum" or "anne"? Dr Rebecca Woods, from Newcastle University, calls upon her training in linguistics and observations from her own home to trace the way children’s experiences shape their first words and the names they use for their parents. Rebecca Woods is a New Generation Thinker on the scheme run by the BBC and the Arts and Humanities Research Council to put academic research on radio. Producer: Ruth Watts You can hear more from Rebecca Woods in a Free Thinking discussion about childhood and play when Young V&A opened - it's available from the programme website and as an Arts & Ideas podcast
