Hi
As per my experience,both can be used but as baby grows cerelac won't be sufficient and little expensive too..on the other side rice+dal powder (porridge )will help baby to get required nutrition as she starts developing physically and mentally .
This also helps preparing little stomach for digesting fruits cookies veggies going further.
Hope its helpful.
Thank you.
If you are making their food at home then I will suggest you use mulling spices in it. This addition would make the taste of the food a lot better so it is necessary to be added.
