How common is it for children to witness childbirth and what issues does it raise? Mother-of-three Viviene Pettitt whose 4 year-old witnessed her son''s birth is in discussion with Jacque Gerrard, director for England at the Royal College of Midwives.**lf****lf**More from The Salon, a series from the BBC World Service looking at women''s lives and identities through their relationship with their hair and their hairdressers around the world. This time we''re in Manchester meeting Daniele, co-owner of a salon with husband Graeme, its chief hairdresser. **lf****lf**As part of Woman''s Hour''s series on knife crime, we talk to DCI Hayley Guest, a senior detective with the Metropolitan Police''s Trident Gang Crime Command with responsibility for tackling gang violence, gun and knife crime.**lf****lf**Composer Charlotte Bray discusses her powerful new work, Falling in the Fire, which has its world premiere at the BBC Proms this weekend.
