Last time when my little boy having the 6 months injection . I ask the doctor the same question and her reply is " around 8 to 9 months as milk have got more nutrient but if your baby don't like milk , you can change to 2 times of congee earlier". So I'll let my boy to have 2 times of congee when he is 8 months old. And now he can finish 1 bowl ( combi ) of congee .
