After birth the concentration of antibodies acquired from the mother decreases rapidly to 0 arbitrary units at months. Antibodies start being produced by cells called in the baby immediately after birth. The total concentration of antibodies in the baby from both sources is arbitrary units at 4 months. The concentration of antibodies acquired from the mother and the concentration of antibodies produced by the baby are the same at months.
