how do I avoid junk food, as every other person has it and some how exposure happens

A. Its You only to expose your child to junk food anyway is also if other person is having it is fine but if you set us a schedule for a child in your child will not ask for too much of junk food when you do not give too much of an exposure will not know what junk food and once in a week you can be what are your child wants to eat separately but still one year is a very small age for that
