At my local hospital partners can now be there the whole time, don't need to prove active labour first and can stay, including overnight, until mum and baby are discharged. The only restriction is that once they are in the hospital they can't leave and come back, so if you've forgotten anything it's tough! The hospital has also said meals will be provided for partners so that they don't need to leave to get food. This hospital has been a little behind the curve on reopening maternity services (water birth, home birth etc) so I am surprised that they are so forward with the partner thing.
