Should grans volunteer in maternity wards?

Sky News are interested in us going on television on Saturday to talk about an NHS scheme that's been piloted in Newport and Hull in understaffed maternity wards.

Grans and experienced mums are being called on to go in and help teach new mothers how to breastfeed, change nappies etc.

Good idea? Community rallying round, as in old days? Do midwives want to do this stuff anyway and are there enough of them? Lovely bonding thing? Or sign of NHS in trouble?
