If you don't have time to 餵2餐粥, why don't you feed baby one time cereal? Just as good and the best thing is, only takes a minute or two to prepare.
My elder daughter never like 食粥, now that she is 2 yrs 5 mths, she still hates it, only took cereal ever since she was a 6-month old.
My 2nd daughter is the same, eating 2 x cereal a day. Have not yet tried 食粥, may be she won't like it neither but nevermind la, they will still grow without eating congee.
