I've been doing it on the floor since my lo was a newborn
floor and L of our couch! we have a changing cushion thats designed for a changing table— we just never got the changing table! oops! lol
I always change mine on the floor as it feels safer. The changing table was disposed of after not being used and taking up too much space.
Put changing mat on the settee or something for your husband
Bed
Mine’s a wriggly boy so the bed or the sofa are the only safe places to change him
Just on the floor or bed and have done since newborn x
Honestly I have to wrestle my 18 month old on the floor to change him, thank god for laminate floor and zoflora!
Setup ontop a long and wide chest of drawers. I’ve seen this on most YouTube videos of how people have their changing setup
