Hi happymrskoh,
Bottled food like Heinz, Gerber, HT has no preservatives. Somehow, my kids only like Heinz. I guess Heinz taste better.
I have to start my kids as early as 4 mths with cereal as both of them start to reject milk when they were ard 4 mths old.
When you buy the Heinz Baby Rice Cereal, you can follow the instructions on how to start your baby with feeding....You start off with 1 teaspoon of rice cereal mixed with milk and increase qty gradually over about 1 week. If your baby can sponstaneously let you feed after that, that shows that she is ready for solid food. But, do give your baby diluted fruit juices as cereal can be quite heaty.
