I use only normal rice for baby porridge because some articles claim baby rice tend to have higher level of arsenic (bit confuse so best to soak any rice for few hours before cooking). I blanch 1-2 finger long pork bone with hot water and then use them for cooking porridge. It has lot calcium and other minerals needed for active baby learning to stand and crawl. Alternatively, you can also make bone broth from other sources and use them for porridge base. Then add carrot, scallops, dried oysters or other desired ingredients into it if you want.
I used organic baby germ rice to cook baby porridge because it is more nutritious and stickier than normal rice. I usually just add Balai thread fish or minced meat together with the washed rice in the rice cooker.
