The infant's maturing immune system first produces IgM antibodies. This is because they are the first antibodies to be produced in response to infection or vaccination and play a critical role in initiating the immune response. Over time, the infant's immune system will begin to produce other classes of antibodies, such as IgG and IgA, as it becomes more mature.
