Till how many years should we give milk twice daily? Can we start giving beet root and carrot juice starting now?

A. If your child likes to have milk you should give milk every day at least once or twice and that if your child likes to have it and juices are not advisable so you can go for giving proper vegetables to the child if you want to give juice only you can give me two and carrot juice to the child but no additional sugar should be there and you can also add some berries gooseberries into them
