We started around 8 months or so. We gave shredded chicken at first and she loved it, then after a few weeks I'd give her turkey cold cuts (Healthy Choice- less sodium and additives) cut into strips. Around 10-11 months I started giving her small amounts of ground beef- whatever we were eating for dinner.

She had her first steak the other night and absolutely looooooved it. I cut it up really small though because it was sort of chewy and I made sure it was cooked well done.
