At 12 months, I was providing soft cooked veggies (carrots, green beans, small amounts of spinich and kale...things like that), soft cooked beans squished a little, but still solid enough to pick up (like canned red beans), and soft fruits like banana and avacados cut into small pieces, along with expressed breast milk. Daycare thought I was a little nutty, but they feed those kids processed crap (IMHO). I have relented a little through her 2nd year of life, but I shake my head at some of the stuff they offer the kids.
I never served my 2 youngest children any pureed food...I waited until they could eat "table food" to start solids (around 9 months), but made sure it was soft and not a major choking hazard. They ate what we ate, but I wasn't faced with any allergy issues so you probably need to account for that in your desicions for what you send.
