Did you use a Lilla Kuddis/goigoi pillow at night?

DS has one for naps as he has a flat head on one side. He loves it and sleeps really well on it
At night I settle him on it and leave him on it til I go to sleep (so I'm watching him while he's on it) but he sleeps so much better on it I'm debating whether to leave him on it all night.

I know the advice and guidance is not to, he's six months old, but I also know in Sweden they are recommended for babies from birth. I'm in a bit of a dilemma because he's really not sleeping, but will sleep beautifully on the pillow.
My own fault for using it for naps I suppose.

I know there is risk to be managed here and I'm not sure I can bring myself to do it, but just wondered if other people let their babies sleep on them at night?
