puree at 8mos

My lo is turning 8mos by this week, but still di pa din sya nakakakain ng minced or kahit mashed food. Nagtry na kasi ako ng mashed pero masuka suka sya at umiiyak, so I always blend her food. She doesn't have any teeth yet, so yun lang nagpapakalma sakin kung bakit di pa sya nakakanguya. Is that normal or should I worry, dahil may mga kasabayan syang nakakanguya na. Thanks in advance.
