Not sure. I know my newborns wriggled themselves into some pretty awkward positions in the rocker.
The other thing is bedding, could be a pain getting the cover dry after poosplosions, or finding a bedding system that would stay secure and be safe for bub.

They're great for supervised day sleeps, but I'm not sold on nights, and I'm pretty relaxed about these things as parents go...
If you're planning on more than one bub, a cradle or bassinet might not be a bad investment, and there are plenty to be gotten second hand. Otherwise bub could go straight to the cot, but they don't fit through doorways, so not so convenient for moving around.

All the best figuring something safe and convenient out! xo
