Why mother with Rh- sensetize not sensetize to the fist fetus with Rh plus but sensetize to the second one?

When Rh negative mother carries Rh positive fetus, mother's immune system will not react because most of the time , during the first pregnancy ,fetomaternal blood will not mix. This will happen at the time of parturition and when mother's immune system detects Rh + , it starts producing antibodies and for this it takes at least 3 week and this will have memory. So in her second pregnancy if in case fetomaternal blood are encountered, mothers immune system start destroying the blood cells of the fetus. This case is known as ErythroBlastosis Foetalis or Hemolytic Disease in new born (HDN)
