Interviewer instructions
This question is similar to BM10 but is specifically designed to probe the time that has passed since the last birth. For example, if Ahmad is reported to be her last birth, and he was born in 2004, ask, “Have you had any live births since the birth of Ahmad?”
If the woman tells you there was a birth since Ahmad, add that birth to the end of the birth history. Then ask BH2-BH10 for that birth, and you may also have to correct the information in CM3-CM11. If, however, there was no birth after Ahmad, record 'No'.
