Infant Feeding Service Organized. Chicago- One of the most novel new businesses started in Chicago in many a day is the new infant feeding service which specializes in any feeding formula which attending physicians specify for babies. The service keeps a card file of the formula for the baby as prescribed by the doctor and the times they are to be taken. Deliveries are made accordingly. Although the new business has just been organized it is growing very rapidly.
