Wendy,
can mix vege and fruits puree in the rice cereals ah? My PD advise me to give my baby porridge with chicken, pork or beef. Start with these 3 first, one at a time. In other words, introduce 1 meat for 5-6 days then another for 5-6 days. Don't start with fish first as fish are most likely to cause allergies as compared with pork, chicken and beef. thereafter, start to add vege into the porridge like broccoli, spinach.
