can we give milk only once in a day to baby

A. But Why is that you should try to give milk at least 4 to 5 times in a day to the child at this age because you do not give too many meals in a day so of course you should cover up the entire time with Milk and slowly gradually you shift down to 3 times in a day with milk than two times but as of now try to give at least 4 to 5 times
