8 month old solids, help

I dont know if shes eating enough. She seems fine and mostly just has breast milk. Starting at 5 months she had some purees and cereal and seemed to enjoy them...for maybe a month tops. Then she was completely over it and won't take purees or cereal. She wants solid food but has no teeth. I feed her tiny pieces of soft chicken and soft cheese, soft boiled fruit and veggies but it's not a lot. If it's soft lime a puree it better be plain yogurt and she loves it. Oh and she has no teeth!
