Mine had visiting for mum's own family, including children, for about 12 hours of the day.
Some families see it as a day out, fun for all the family - but sadly not for anyone else on the ward as toddlers duck under curtains for a good long gawp at the new mum struggling to breastfeed, the dad of the tribe falls asleep in the chair, snoring, while the children rampage around the ward, using a new baby's bassinet (not their sibling's) as a scooter, etc.
Should midwives be on crowd control duty and kick them out? Or do new mums have a right to have their family with them, however annoying that family may be to someone else? Should visiting hours be broken up with quiet periods around eg lunch, etc on postnatal wards? Or should there be shorter periods of time available for children to visit their new sibling? I know not everyone has people they can leave their older children with, so that can make it difficult.
