I think we started around 4 months and he was still too small so I had to put a folded blanket underneath so his feet were comfortably on the ground. I'd say it just depends on her size and neck strength.
DD was 3.5 months, I probably could have started earlier but she is on the small side. I still have telephone books underneath or her feet won't touch. But she LOVES it!!!
My guys are 3.5 months adjusted and I've put them in it but their feet don't reach the ground so I put a rolled up towel in the seat with them so they don't fall forward but then they can't reach they toys! THey still like it htough!
