First Feed - Rice Cereal

Evangeline has had her first try of solid food just before she reached 6th mth. She had rice cereal mixed with mummy's breastmilk. She did not reject the first taste and was slowly enjoying her food. Then, we introduced carrots puree, potato puree and pear puree to her. Somehow, she was not used to the new flavours of her food and showed us the "yucks!" face. And she even made the vomitting kind of expression with the sound - yuoak! Does that mean she didn't like the food? We are not very sure but grandma wanted to try her on porridge.... which mummy thinks we should take it easily and let her get used to her rice cereal before doing so. Any comments???
