Solid foods

My daughter is 7 month. She has her bottom 2 teeth. She gets purées and formula and I also give her the yogurt melts. She looks like she is trying to chew the yogurt melts with her gums. Can I give her something a little more solid to eat (the Crunchies or something like that). Can I give her the purées with the little bits? Should I wait until her top 2 teeth come in before trying either of those? I’m kind of afraid she will choke on either.

Suggestions please!
