This is so true, my dear SIL was told by her mother she couldnt conceive when breastfeeding, and her second daughter was born on her first daughter's first birthday. I also know a pair of siblings only 8 months apart, because the second child was concieved about 6 weeks after the birth of the first one and was born early. I could tell more tales but they arent for this list. So alhtough medics tell women it is good to wait at least year before trying for another baby, many people have had another child within the year Liz >Hi Keith, > >I don't think you can have such a set time frame between the birth of one >child and the next. > >My older sister is thirteen months older than I am. > >My two youngest children have eleven months between them.
