C.S.
Although she's 6 months old and the pediatrician has told you she is ready for solids, I wouldn't try to force her to eat it. I have an 8 month old that just started eating solids in the last 4 weeks. I tried at 5 and 6 months with her with no luck - she didn't want it or would push it out of her mouth. If you wait a few weeks perhaps it would help. Have you tried other foods besides cereal? I know my little girl won't eat cereal unles it's mixed with fruit.
