Rice cereal- Q

A friend of mine has a 4 month old that is already eating rice cereal, and I have a five almost six month old- can I give her rice cereal even though she is not sitting up on her own, or is it supposed to be mixed in with her milk? I thought I read somewhere that I should wait until baby is sitting up on her own.
