You seem to be giving a nice mixture of feeds for the baby.
If he is not crying for more and passing stools normally you need not worry.
You can add one type of fruit juice in between and can add another meal of cerelac if possible in the day time.
Do not add ghee to cerelac-it will make it heavy to digest and also will delay the next feed.Fat is there in milk also.child,s weight at 1 year should be 3 times the birthweight
,then it is normal growth!!!! keep it up!,,
