So after a baby is born they have to be seen in the USA at 2 days, 2 weeks, 2, 4, 6, 9, 12, 18, 24 months and so more. They say to check for development. I understand for first ones. It sounds reasonable. I mean I have a book to watch for milestones and understand that each child developments differently. Do you think the frequency is also done to push so many vaccines and also in part payment to the doctor for the visit?
