I think it depends where you look, @CourtneeLuv. I think that there are so many wonderful MNers giving advice and support on so many subjects - pregnancy, childbirth, breastfeeding, weaning, mental illness, domestic violence, ereavement, and abuse, schools and schooling issues. Then there are the hilarious threads posted by MNers who don’t mind sharing their pratfalls for the amusement of MN - you can lose hours in the entertainment of Mumsnet Classics - Elderly Korean Lady, Auntie Tantrums babysits (“Well - that went well”), Mexican House Thief, Honeydragon dying the baby blue, “Your Minge” (where a MNer carefully removed her tanking bottoms at the poolside and didn’t realise until her husband came out of the changing rooms, pointed across the pool and said “your minge” and she concluded she must change her name and never go to that pool again).
Or the charity work done by Woolly Hugs, which began as a MN group knitting project to make a blanket to send to a MNer whose little boy had died after surgery to remove a brain tumour, and mushroomed into a group that makes blankets for MNers who have lost a spouse or child, and also blankets for children in hospital, for women undergoing treatment for breast cancer, for refugees, for premature babies who are stillborn (so the hospital has something to wrap them in that isn’t just clinical), and also runs two online craft sales each year, that raise money for various different charities - not terribly joyless.
