My daughter has gone through similar phases. Don't worry, at 10 months she is not depending on the food you give her for her nutritional needs. The formula or breast milk you give her is where she is getting all the nutrients she needs right now. Think of this stage as the practice eating stage. She is just getting to know what eating food is all about. Be consistant in what you give her. At 10 months I stopped feeding my daughter jarred foods and we went straight to table foods. Surprisingly her eating got better then. I also found that if we ate our meals with her, she is a better eater.
So basically what I am saying is, don't put so much pressure on yourself or your daughter at this point in time when it comes to consuming food. She will get the hang of it eventually. Just try to make the eating experience a fun one.
