baby is 5-months old! what brand of infant cereal should I start with? I wanna start my first solid introduction to her this weekend. what should I buy? *excited!*

Have a friend who started with Gerber Rice Cereal (when her baby was 4.5months old). http://www.iherb.com/Gerber-Rice-Cereal-Single-Grain-8-oz-227-g/48865 She read that it is better to start with single grain before moving on to multigrain. Also that white rice is easier to digest as compared to brown rice.
