You brought a range of things to hospital to wear for the first few post-natal days.
Firstly, there are some pyjamas with a traditional button front for easy breastfeeding opening. But they won’t do because of the catheter going down your leg.
You brought a night shirt/night dress, which is good for the catheter, but to feed you have to be, well, pretty much naked.
You sit there feeling all kinds of uncomfortable to a series of new levels. Then the epiphany:
You need skirt-pyjamas with a traditional pyjama top!
This does not exist.
So you wear unsatisfactory night attire until you are free of the catheter.
