Anyone has been using a baby bjorn bouncer from birth?

I tried to use from birth but she started crying straight away and I was thinking to sell it. But when she has reached the age of 8 weeks I tried again and she was okay. And it’s the best way to get her to sleep by day.

I used it when my boy was 3 weeks old but put it on the lowest setting. We didn't use it much then but use it more now he is 13 weeks xx
