I think, like any other baby equipment, moderation and common sense is in order Anything they use all day, every day is going to be bad for them.

Ahh, they love to scare us don't they? My mchn thought 'equipment' (slings, bumbos, bouncers, prams, even car seats) was the devil's work and recommended bubs should spend no more than 1 hour in any 'equipment' on any given day I think she either had forgotten or just doesn't know how hard it is to get stuff done with a baby around!
