My son is half-Chinese and had rice porridge as one of his first solids after six months. My in-laws made it extra-bland and made sure there were no chunks in it. My husband and all his siblings grew up on the stuff. The only real difference is that the homemade porridge is not fortified with iron like the commercially-made cereals. If your baby is drinking iron-fortified formula then give the homemade porridge and don't worry about iron. If you are still breastfeeding you might want to ask the doctor if you need to supplement with iron drops. Pediatricians seem to have differing opinions on that.
