Baby pushes cereal out of her mouth

Rajsi

My baby will be 6 months old this weekend. I am trying to feed her rice and oatmeal cereals for 3-4 weeks now. It seems like she still does not know how to swallow food. Everytime I put cereal in her mouth, she pushes it out. She reaches out to my food and seems interested. She even open her mouth when I bring the spoon near to feed her. I am planning to start purees next week. What if she does the same? Any suggestions??
