Chatting about this to my sister last night, when she had dd1 visiting times were the same as the rest of the hospital, with the exception that dads could stay longer, (8-8) but just them, if they had other dc with them then they had to leave at usual times, and had to leave ward at meal times, She remembers that all the men left at tea time, and the women who had straight forward births with no complications etc mostly left on the same day/next morning. Sister had trouble establishing feeding so spent two nights in, the people who helped her the most were the other mums on the ward, sister was 18 and said she will never forget the advice she received from other mums who had a wide range of experiences. Her dp was lovely but he didn't get it, so made himself useful by getting stuff ready at home for her (he did a brill job, mum turned up as she had seen his version of clean, but he did a fantastic job)
When she had dd2 she was a little older and thankfully she had a straightforward birth and feeding established quickly, at visiting time she was shocked at visiting time when one of the women's partners came into the ward, sister knew him and also knew he had served time for rape. He kept himself to himself and didn't bother anyone, but I understand why sis felt uncomfortable by him just being there. She knew she was leaving that day told herself to stop being daft, but said if she had to sleep the night with him when she had dd1 she prob wouldn't have had anymore children because two days of feeling unease would have put her off. Not because she thought he'd attack her, just knowing what he had done made her uneasy.
She said that if we end up in a situation were all partners can stay, she think there should be some system, such as a crb check at the start/midway of pregnancy so that partners who had convictions against women such as dv or sexual assault, could be refused constant access to the wards. She said it wouldn't stop all abusive partners because not all are convicted but if those with certain convictions would be prevented from working with the mums, then they should be prevented from constant access on wards too.
Fwiw, she knows NAMALT but those who are should not be on wards 24/7. A certain famous footballer who is having a baby would prob have private care, but she'd think most women would not be happy having to sleep on a ward with him, and if they knew the convictions of the man on the ward when she had dd2 they would feel uncomfortable too. She doesn't think it will happen though, and that if we end up with a blanket all partners allowed, then many women are in for a miserable time.
