I think it's completely normal for visitors a day or 2 after mum and baby are home from hospital, and if the woman is happy with it even a hospital visit.
Of course the mothers needs should be put first but I think it's really off to keep family away for a prolonged period of time.
Unless you've had a particularly traumatic birth or illness afterwards it's not exactly crazy for close family and friends to want to visit.
Though on that note, I've noticed in recent years, probably due to an increase in vloggers etc on social media, so many women now say they had a traumatic birth and it actually sounds pretty text book! Painful, long, hard, exhausting, but not traumatic in the literal sense of the word. I think some people enjoy the drama of it.
My friend kept saying traumatic birth last year, she had a full term spontaneous labour with a variety of pain relief available, no tearing or stitches, healthy baby, no lasting effects from the labour, it was a normal healthy birth! Home the same day.
My other friend mentioned in the same conversation that she tore from her bum to her vagina after an emergency situation with forceps and needed major surgery to repair it before being discharged. She soon stopped saying she'd been through a trauma
